Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables protein phosphatase binding activity and protein phosphorylated amino acid binding activity. Involved in several processes, including negative regulation of I-kappaB phosphorylation; negative regulation of MAPK cascade; and negative regulation of cytokine production. Acts upstream of or within several processes, including hematopoietic progenitor cell differentiation; phagocytosis; and positive regulation of phagocytosis. Located in plasma membrane. Is expressed in several structures, including adrenal gland; cartilage; central nervous system; genitourinary system; and retina. Orthologous to human SIRPA (signal regulatory protein alpha).
