Summary: Predicted to enable non-membrane spanning protein tyrosine kinase activity. Involved in T cell receptor signaling pathway; adaptive immune response; and positive regulation of cytokine production. Acts upstream of or within NK T cell differentiation. Predicted to be located in cytosol; nucleolus; and nucleoplasm. Predicted to be active in plasma membrane. Is expressed in several structures, including hemolymphoid system; lung; male reproductive gland or organ; stomach mesentery; and vertebral axis musculature. Orthologous to human TXK (TXK tyrosine kinase). [provided by Alliance of Genome Resources, Nov 2024]

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.
