Members of the MIP superfamily function as membrane channels that selectively transport water, small neutral molecules, and ions out of and between cells. The channel proteins share a common fold: the N-terminal cytosolic portion followed by six transmembrane helices, which might have arisen through gene duplication. On the basis of sequence similarity and functional characteristics, the superfamily can be subdivided into two major groups: water-selective channels called aquaporins (AQPs) and glycerol uptake facilitators (GlpFs). AQPs are found in all three kingdoms of life, while GlpFs have been characterized only within microorganisms. Length = 228

1.A.8 The Major Intrinsic Protein (MIP) FamilyThe MIP family is large and diverse, possessing over 100 members that all form transmembrane channels. These channel proteins function in water, smallcarbohydrate (e.g., glycerol), urea, NH3, CO2 and possibly ion transport by an energy independent mechanism. They are found ubiquitously in bacteria, archaeaand eukaryotes. The MIP family contains two major groups of channels: aquaporins and glycerol facilitators.The known aquaporins cluster loosely together as do the known glycerol facilitators. MIP family proteins are believed to form aqueous pores that selectively allow passive transport of their solute(s) across the membrane with minimal apparent recognition. Aquaporins selectively transport water (but not glycerol) while glycerol facilitators selectively transport glycerol but not water. Some aquaporins can transport NH3 and CO2. Glycerol facilitators function as solute nonspecific channels, and may transport glycerol, dihydroxyacetone, propanediol, urea and other small neutral molecules in physiologically importantprocesses. Some members of the family, including the yeast FPS protein (TC #1.A.8.5.1) and tobacco NtTIPA may transport both water and small solutes [Transport and binding proteins, Unknown substrate].

Members of the MIP superfamily function as membrane channels that selectively transport water, small neutral molecules, and ions out of and between cells. The channel proteins share a common fold: the N-terminal cytosolic portion followed by six transmembrane helices, which might have arisen through gene duplication. On the basis of sequence similarity and functional characteristics, the superfamily can be subdivided into two major groups: water-selective channels called aquaporins (AQPs) and glycerol uptake facilitators (GlpFs). AQPs are found in all three kingdoms of life, while GlpFs have been characterized only within microorganisms.

These include: Mammalian major intrinsic protein (MIP). MIP is the major component of lens fibre gap junctions. Mammalian aquaporins []. These proteins form water- specific channels that provide the plasma membranes of red cells and kidney prox imal and collecting tubules with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Soybean nodulin-26, a major component of the peribacteroid membrane induced during nodulation in legume roots after Rhizobium infection. Plants tonoplast intrinsic proteins (TIP). There are various isoforms of TIP : alpha (seed), gamma, Rt (root), and Wsi (water-stress induced). These proteins may allow the diffusion of water, amino acids and/or peptides from the tonoplas t interior to the cytoplasm. Bacterial glycerol facilitator protein (gene glpF), which facilitates the mo vement of glycerol across the cytoplasmic membrane. Salmonella typhimurium propanediol diffusion fac ilitator (gene pduF). Yeast FPS1, a glycerol uptake/efflux facilitator protein. Drosophila neurogenic protein 'big brain' (bib). This protein may mediate in tercellular communication; it may functions by allowing the transport of certain molecules(s) and thereby sending a signal for an exodermal cell to become an ep idermoblast instead of a neuroblast. Yeast hypothetical protein YFL054c. A hypothetical protein from the pepX region of Lactococcus lactis. The structures of various members of the MIP family have been determined by means of X-ray diffraction [, , ], revealing the fold to comprise a right-handed bundle of 6 transmembrane (TM) alpha-helices [, , ]. Similarities in the N-and C-terminal halves of the molecule suggest that the proteins may have arisen through tandem, intragenic duplication of an ancestral protein that contained 3 TM domains []. Some of the proteins in this group are responsible for the molecular basis of the blood group antigens, surface markers on the outside of the red blood cell membrane. Most of these markers are proteins, but some are carbohydrates attached to lipids or proteins []. Aquaporin-CHIP (Aquaporin 1) belongs to the Colton blood group system and is associated with Co(a/b) antigen.; GO: 0005215 transporter activity, 0006810 transport, 0016020 membrane; PDB: 3NE2_A 2C32_A 1YMG_A 2B6P_A 3C02_A 2B5F_D 3CN6_A 3CN5_A 1Z98_M 3CLL_A ....

Members of the MIP superfamily function as membrane channels that selectively transport water, small neutral molecules, and ions out of and between cells. The channel proteins share a common fold: the N-terminal cytosolic portion followed by six transmembrane helices, which might have arisen through gene duplication. On the basis of sequence similarity and functional characteristics, the superfamily can be subdivided into two major groups: water-selective channels called aquaporins (AQPs) and glycerol uptake facilitators (GlpFs). AQPs are found in all three kingdoms of life, while GlpFs have been characterized only within microorganisms.

These include: Mammalian major intrinsic protein (MIP). MIP is the major component of lens fibre gap junctions. Mammalian aquaporins []. These proteins form water- specific channels that provide the plasma membranes of red cells and kidney prox imal and collecting tubules with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Soybean nodulin-26, a major component of the peribacteroid membrane induced during nodulation in legume roots after Rhizobium infection. Plants tonoplast intrinsic proteins (TIP). There are various isoforms of TIP : alpha (seed), gamma, Rt (root), and Wsi (water-stress induced). These proteins may allow the diffusion of water, amino acids and/or peptides from the tonoplas t interior to the cytoplasm. Bacterial glycerol facilitator protein (gene glpF), which facilitates the mo vement of glycerol across the cytoplasmic membrane. Salmonella typhimurium propanediol diffusion fac ilitator (gene pduF). Yeast FPS1, a glycerol uptake/efflux facilitator protein. Drosophila neurogenic protein 'big brain' (bib). This protein may mediate in tercellular communication; it may functions by allowing the transport of certain molecules(s) and thereby sending a signal for an exodermal cell to become an ep idermoblast instead of a neuroblast. Yeast hypothetical protein YFL054c. A hypothetical protein from the pepX region of Lactococcus lactis. The structures of various members of the MIP family have been determined by means of X-ray diffraction [, , ], revealing the fold to comprise a right-handed bundle of 6 transmembrane (TM) alpha-helices [, , ]. Similarities in the N-and C-terminal halves of the molecule suggest that the proteins may have arisen through tandem, intragenic duplication of an ancestral protein that contained 3 TM domains []. Some of the proteins in this group are responsible for the molecular basis of the blood group antigens, surface markers on the outside of the red blood cell membrane. Most of these markers are proteins, but some are carbohydrates attached to lipids or proteins []. Aquaporin-CHIP (Aquaporin 1) belongs to the Colton blood group system and is associated with Co(a/b) antigen.; GO: 0005215 transporter activity, 0006810 transport, 0016020 membrane; PDB: 3NE2_A 2C32_A 1YMG_A 2B6P_A 3C02_A 2B5F_D 3CN6_A 3CN5_A 1Z98_M 3CLL_A ....
