What's a GeneRIF?

to understand actin-mediated change in protein localization during acrosome reaction, distribution of CAPZA3 was analyzed; like IZUMO1, CAPZA3 shows dynamic pattern of localization; movements follow different temporal pattern than changes seen with IZUMO1
Title: Analysis of CAPZA3 localization reveals temporally discrete events during the acrosome reaction.
These observations strongly suggest the missense mutation in Capza3 is responsible for the mutant phenotype of repro32/repro32 sperm and regulation of F-actin dynamics
Title: A missense mutation in the Capza3 gene and disruption of F-actin organization in spermatids of repro32 infertile male mice.
CPalpha3 might play an important role in sperm morphogenesis and/or sperm function
Title: Characterizing mouse male germ cell-specific actin capping protein alpha3 (CPalpha3): dynamic patterns of expression in testicular and epididymal sperm.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
