該基因編碼Rho-GTPase激活蛋白超家族的一個成員編碼蛋白可能作為Rho-GTPase激活蛋白發揮作用這種基因的改變可能與多種疾病有關，包括類風濕性關節炎、腹腔疾病和多發性硬化癥。交替剪接導致編碼不同亞型的多個轉錄變體。
This gene encodes a member of the Rho GTPase-activator protein superfamily. The encoded protein may function as a Rho GTPase-activating protein. Alterations in this gene may be associated with several diseases, including rheumatoid arthritis, celiac disease, and multiple sclerosis. Alternate splicing results in multiple transcript variants encoding distinct isoforms.
