Gelsolin repeats occur in gelsolin, severin, villin, advillin, villidin, supervillin, flightless, quail, fragmin, and other proteins, usually in several copies. They co-occur with villin headpiece domains, leucine-rich repeats, and several other domains. These gelsolin-related actin binding proteins (GRABPs) play regulatory roles in the assembly and disassembly of actin filaments; they are involved in F-actin capping, uncapping, severing, or the nucleation of actin filaments. Severing of actin filaments is Ca2+ dependent. Villins are also linked to generating bundles of F-actin with uniform filament polarity, which is most likely mediated by their extra villin headpiece domain. Many family members have also adopted functions in the nucleus, including the regulation of transcription. Supervillin, gelsolin, and flightless I are involved in intracellular signaling via nuclear hormone receptors. The gelsolin_like domain is distantly related to the actin depolymerizing domains found in cofilin and similar proteins. Length = 113

>PF00626 Gelsolin: Gelsolin repeat; InterPro: IPR007123 Gelsolin is a cytoplasmic, calcium-regulated, actin-modulating protein that binds to the barbed ends of actin filaments, preventing monomer exchange (end-blocking or capping) []
It can promote nucleation (the assembly of monomers into filaments), as well as sever existing filaments. In addition, this protein binds with high affinity to fibronectin. Plasma gelsolin and cytoplasmic gelsolin are derived from a single gene by alternate initiation sites and differential splicing. Sequence comparisons indicate an evolutionary relationship between gelsolin, villin, fragmin and severin []. Six large repeating segments occur in gelsolin and villin, and 3 similar segments in severin and fragmin. While the multiple repeats have yet to be related to any known function of the actin-severing proteins, the superfamily appears to have evolved from an ancestral sequence of 120 to 130 amino acid residues [].; PDB: 3FG6_F 1RGI_G 2FGH_A 1D0N_B 3EGD_B 2NUP_B 2NUT_B 3EGX_B 1JHW_A 1J72_A ....
>PF00241 Cofilin_ADF: Cofilin/tropomyosin-type actin-binding protein; InterPro: IPR002108 The actin-depolymerising factor homology (ADF-H) domain is an ~150-amino acid motif that is present in three phylogenetically distinct classes of eukaryotic actin-binding proteins [, , ]: ADF/cofilins, which include ADF, cofilin, destrin, actophorin, coactosin, depactin and glia maturation factors (GMFs) beta and gamma
ADF/cofilins are small actin-binding proteins composed of a single ADF-H domain. They bind both actin-monomers and filaments and promote rapid filament turnover in cells by depolymerising/fragmenting actin filaments. ADF/cofilins bind ADP-actin with higher affinity than ATP-actin and inhibit the spontaneous nucleotide exchange on actin monomers Twinfilins, which are actin monomer-binding proteins that are composed of two ADF-H domains Abp1/Drebrins, which are relatively large proteins composed of an N-terminal ADF-H domain followed by a variable region and a C-terminal SH3 domain. Abp1/Drebrins interact only with actin filaments and do not promote filament depolymerisation or fragmentation Although these proteins are biochemically distinct and play different roles in actin dynamics, they all appear to use the ADF-H domain for their interactions with actin. The ADF-H domain consists of a six-stranded mixed beta-sheet in which the four central strands (beta2-beta5) are anti-parallel and the two edge strands (beta1 and beta6) run parallel with the neighbouring strands. The sheet is surrounded by two alpha-helices on each side [, , ].; GO: 0003779 actin binding, 0005622 intracellular; PDB: 1AK6_A 1AK7_A 1V6F_A 2L72_A 1CFY_A 1QPV_A 1COF_A 1TVJ_A 1X67_A 3L50_A ....
