Predicted to enable SH2 domain binding activity; enzyme binding activity; and signaling adaptor activity. Predicted to be involved in cell surface receptor signaling pathway; intracellular signal transduction; and positive regulation of gene expression. Predicted to be located in cytoplasmic ribonucleoprotein granule; cytosol; and plasma membrane. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in agammaglobulinemia and agammaglobulinemia 4. Orthologous to human BLNK (B cell linker). [provided by Alliance of Genome Resources, Apr 2022]
