Genes affected

RALGAPB (HGNC:29221): (Ral GTPase activating protein non-catalytic subunit beta) Enables protein heterodimerization activity. Predicted to be involved in activation of GTPase activity. Predicted to act upstream of or within Ral protein signal transduction; regulation of exocyst localization; and regulation of protein localization.
