CC -!- FUNCTION: Non-receptor tyrosine kinase that plays a redundant role with
CC ITK in regulation of the adaptive immune response. Regulates the
CC development, function and differentiation of conventional T-cells and
CC nonconventional NKT-cells. When antigen presenting cells (APC) activate
CC T-cell receptor (TCR), a series of phosphorylation leads to the
CC recruitment of TXK to the cell membrane, where it is phosphorylated at
CC Tyr-420. Phosphorylation leads to TXK full activation. Contributes also
CC to signaling from many receptors and participates in multiple
CC downstream pathways, including regulation of the actin cytoskeleton.
CC Like ITK, can phosphorylate PLCG1, leading to its localization in lipid
CC rafts and activation, followed by subsequent cleavage of its
CC substrates. In turn, the endoplasmic reticulum releases calcium in the
CC cytoplasm and the nuclear activator of activated T-cells (NFAT)
CC translocates into the nucleus to perform its transcriptional duty.
CC Plays a role in the positive regulation of IFNG transcription in T-
CC helper 1 cells as part of an IFNG promoter-binding complex with PARP1
CC and EEF1A1 (PubMed:11859127, PubMed:17177976). Within the complex,
CC phosphorylates both PARP1 and EEF1A1 (PubMed:17177976). Phosphorylates
CC also key sites in LCP2 leading to the up-regulation of Th1 preferred
CC cytokine IL-2. Phosphorylates 'Tyr-201' of CTLA4 which leads to the
CC association of PI-3 kinase with the CTLA4 receptor.
