Description

Predicted to have 1-phosphatidylinositol-3-kinase activity; ATP binding activity; and phosphatidylinositol bisphosphate kinase activity. Involved in regulation of collateral sprouting in absence of injury. Human ortholog(s) of this gene implicated in several diseases, including CLOVES syndrome; Cowden syndrome; breast cancer (multiple); colorectal cancer (multiple); and cutaneous Paget's disease. Is expressed in eye. Orthologous to human PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha).
