Automated description from the Alliance of Genome Resources
Exhibits several functions, including CD4 receptor binding activity; protein antigen binding activity; and protein phosphatase binding activity. Involved in several processes, including positive regulation of macromolecule metabolic process; protein phosphorylation; and regulation of T cell differentiation. Localizes to the cell-cell junction. Colocalizes with the plasma membrane. Human ortholog(s) of this gene implicated in primary immunodeficiency disease. Is expressed in several structures, including 2-cell stage embryo; nervous system; neural ectoderm; sensory organ; and thymus primordium. Orthologous to human LCK (LCK proto-oncogene, Src family tyrosine kinase).
