Protein Structure

UniProt Annotation

Function

Could be involved in oogenesis. Involved in the regulation of endosome dynamics. Implicated in a novel signal transduction pathway, in which isoform 3 and CSK are sequentially activated by RHOD to regulate the motility of early endosomes through interactions with the actin cytoskeleton. {ECO:0000269PubMed:12577064}.

Subcellular Localization

Isoform 3: Cytoplasm, cytosol. Early endosome. Note=Isoform 3 is cytosolic but when coexpressed with RHOD, the 2 proteins colocalize to early endosomes.

Disease Associations

Premature ovarian failure 2A (POF2A) [MIM:300511]: An ovarian disorder defined as the cessation of ovarian function under the age of 40 years. It is characterized by oligomenorrhea or amenorrhea, in the presence of elevated levels of serum gonadotropins and low estradiol. {ECO:0000269PubMed:9497258}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Expressed in testis, ovary, small intestine, prostate, lung, liver, kidney and leukocytes.
