>gnl|CDD|100016 cd02187, beta_tubulin, The tubulin superfamily includes five distinct families, the alpha-, beta-, gamma-, delta-, and epsilon-tubulins and a sixth family (zeta-tubulin) which is present only in kinetoplastid protozoa
The alpha- and beta-tubulins are the major components of microtubules, while gamma-tubulin plays a major role in the nucleation of microtubule assembly. The delta- and epsilon-tubulins are widespread but unlike the alpha, beta, and gamma-tubulins they are not ubiquitous among eukaryotes. The alpha/beta-tubulin heterodimer is the structural subunit of microtubules. The alpha- and beta-tubulins share 40% amino-acid sequence identity, exist in several isotype forms, and undergo a variety of posttranslational modifications. The structures of alpha- and beta-tubulin are basically identical: each monomer is formed by a core of two beta-sheets surrounded by alpha-helices. The monomer structure is very compact, but can be divided into three regions based on function: the amino-terminal nucleotide-binding region, an intermediate taxol-binding region and the carboxy-terminal region which probably constitutes the binding surface for motor proteins. Length = 425
This family includes the tubulin alpha, beta and gamma chains, as well as the bacterial FtsZ family of proteins. Members of this family are involved in polymer formation. FtsZ is the polymer-forming protein of bacterial cell division. It is part of a ring in the middle of the dividing cell that is required for constriction of cell membrane and cell envelope to yield two daughter cells. FtsZ and tubulin are GTPases. FtsZ can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in eubacteria and archaea. Tubulin is the major component of microtubules. Length = 210

>PF10644 Misat_Tub_SegII: Misato Segment II tubulin-like domain; InterPro: IPR019605 The misato protein contains three distinct, conserved domains, segments I, II and III and is involved in the regulation of mitochondrial distribution and morphology []
This entry represents misato segment II. Segments I and III are common to tubulins (IPR003008 from INTERPRO), but segment II aligns with myosin heavy chain sequences from Drosophila melanogaster (Fruit fly, P05661 from SWISSPROT), rabbit (P04460 from SWISSPROT), and human. Segment II of misato is a major contributor to its greater length compared with the various tubulins. The most significant sequence similarities to this 54-amino acid region are from a motif found in the heavy chains of myosins from different organisms. A comparison of segment II with the vertebrate myosin heavy chains reveals that it is homologous to a myosin peptide in the hinge region linking the S2 and LMM domains. Segment II also contains heptad repeats which are characteristic of the myosin tail alpha-helical coiled-coils [].
