Description

Predicted to enable phosphatidylinositol-3,4-bisphosphate 5-kinase activity and phosphatidylinositol-4,5-bisphosphate 3-kinase activity. Acts upstream of or within regulation of collateral sprouting in absence of injury. Is expressed in eye and male organism. Human ortholog(s) of this gene implicated in several diseases, including CLOVES syndrome; Cowden syndrome 5; breast cancer (multiple); cutaneous Paget's disease; and gastrointestinal system cancer (multiple). Orthologous to human PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha).
