Genes affected

SIPA1L1 (HGNC:20284): (signal induced proliferation associated 1 like 1) Predicted to enable GTPase activator activity; actin filament binding activity; and protein kinase binding activity. Predicted to be involved in several processes, including actin cytoskeleton organization; activation of GTPase activity; and regulation of postsynapse organization. Located in actin cytoskeleton and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
