Summary: Enables transmembrane receptor protein tyrosine kinase adaptor activity. Acts upstream of or within Ras protein signal transduction and cell surface receptor protein tyrosine kinase signaling pathway. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; immune system; liver; and lung. Orthologous to human DOK2 (docking protein 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
