Genes affected

CASS4 (HGNC:15878): (Cas scaffold protein family member 4) Enables protein tyrosine kinase binding activity. Involved in several processes, including positive regulation of protein kinase B signaling; positive regulation of protein tyrosine kinase activity; and positive regulation of substrate adhesion-dependent cell spreading. Located in focal adhesion. Part of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
