CAPZA3, Official Symbol CAPZA3provided by HGNC Official Full Name capping actin protein of muscle Z-line subunit alpha 3provided by HGNC Primary source HGNC:HGNC:24205 See related Ensembl:ENSG00000177938 MIM:608722; AllianceGenome:HGNC:24205 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as Gsg3; CAPPA3; HEL-S-86 Summary This gene encodes an actin capping protein, one of the F-actin capping protein alpha subunit family. The encoded protein is predominantly localized to the neck region of ejaculated sperm, other immunohistochemical signals were found in the tail and postacrosomal regions. The encoded protein may also form heterodimers of alpha and beta subunits. This protein may be important in determining sperm architecture and male fertility.
