		+	== Disease ==
		+	[[http://www.uniprot.org/uniprot/BTK_HUMAN BTK_HUMAN]] Defects in BTK are the cause of X-linked agammaglobulinemia (XLA) [MIM:[http://omim.org/entry/300755 300755]]; also known as X-linked agammaglobulinemia type 1 (AGMX1) or immunodeficiency type 1 (IMD1). XLA is a humoral immunodeficiency disease which results in developmental defects in the maturation pathway of B-cells. Affected boys have normal levels of pre-B-cells in their bone marrow but virtually no circulating mature B-lymphocytes. This results in a lack of immunoglobulins of all classes and leads to recurrent bacterial infections like otitis, conjunctivitis, dermatitis, sinusitis in the first few years of life, or even some patients present overwhelming sepsis or meningitis, resulting in death in a few hours. Treatment in most cases is by infusion of intravenous immunoglobulin.<ref>PMID:7880320</ref> <ref>PMID:8013627</ref> <ref>PMID:8162056</ref> <ref>PMID:8162018</ref> <ref>PMID:7849697</ref> <ref>PMID:7849721</ref> <ref>PMID:7809124</ref> <ref>PMID:7849006</ref> <ref>PMID:7711734</ref> <ref>PMID:7633420</ref> <ref>PMID:7633429</ref> <ref>PMID:8634718</ref> <ref>PMID:7627183</ref> <ref>PMID:7897635</ref> <ref>PMID:8723128</ref> <ref>PMID:8695804</ref> <ref>PMID:8834236</ref> <ref>PMID:9280283</ref> <ref>PMID:9260159</ref> <ref>PMID:9545398</ref> <ref>PMID:9445504</ref> <ref>PMID:10220140</ref> <ref>PMID:10678660</ref> <ref>PMID:10612838</ref> Defects in BTK may be the cause of X-linked hypogammaglobulinemia and isolated growth hormone deficiency (XLA-IGHD) [MIM:[http://omim.org/entry/307200 307200]]; also known as agammaglobulinemia and isolated growth hormone deficiency or Fleisher syndrome or isolated growth hormone deficiency type 3 (IGHD3). In rare cases XLA is inherited together with isolated growth hormone deficiency (IGHD).
		+	== Function ==
		+	[[http://www.uniprot.org/uniprot/BTK_HUMAN BTK_HUMAN]] Non-receptor tyrosine kinase indispensable for B lymphocyte development, differentiation and signaling. Binding of antigen to the B-cell antigen receptor (BCR) triggers signaling that ultimately leads to B-cell activation. After BCR engagement and activation at the plasma membrane, phosphorylates PLCG2 at several sites, igniting the downstream signaling pathway through calcium mobilization, followed by activation of the protein kinase C (PKC) family members. PLCG2 phosphorylation is performed in close cooperation with the adapter protein B-cell linker protein BLNK. BTK acts as a platform to bring together a diverse array of signaling proteins and is implicated in cytokine receptor signaling pathways. Plays an important role in the function of immune cells of innate as well as adaptive immunity, as a component of the Toll-like receptors (TLR) pathway. The TLR pathway acts as a primary surveillance system for the detection of pathogens and are crucial to the activation of host defense. Especially, is a critical molecule in regulating TLR9 activation in splenic B-cells. Within the TLR pathway, induces tyrosine phosphorylation of TIRAP which leads to TIRAP degradation. BTK plays also a critical role in transcription regulation. Induces the activity of NF-kappa-B, which is involved in regulating the expression of hundreds of genes. BTK is involved on the signaling pathway linking TLR8 and TLR9 to NF-kappa-B. Transiently phosphorylates transcription factor GTF2I on tyrosine residues in response to BCR. GTF2I then translocates to the nucleus to bind regulatory enhancer elements to modulate gene expression. ARID3A and NFAT are other transcriptional target of BTK. BTK is required for the formation of functional ARID3A DNA-binding complexes. There is however no evidence that BTK itself binds directly to DNA. BTK has a dual role in the regulation of apoptosis.<ref>PMID:9012831</ref> <ref>PMID:11606584</ref> <ref>PMID:16517732</ref> <ref>PMID:16738337</ref> <ref>PMID:16415872</ref> <ref>PMID:17932028</ref>

		+	== Publication Abstract from PubMed ==
		+	Bruton's tyrosine kinase (BTK), a non-receptor tyrosine kinase, is a member of the Tec family of kinases and is essential for B cell receptor (BCR) mediated signaling. BTK also plays a critical role in the downstream signaling pathways for the Fcgamma receptor in monocytes, the Fcepsilon receptor in granulocytes, and the RANK receptor in osteoclasts. As a result, pharmacological inhibition of BTK is anticipated to provide an effective strategy for the clinical treatment of autoimmune diseases such as rheumatoid arthritis and lupus. This article will outline the evolution of our strategy to identify a covalent, irreversible inhibitor of BTK that has the intrinsic potency, selectivity, and pharmacokinetic properties necessary to provide a rapid rate of inactivation systemically following a very low dose. With excellent in vivo efficacy and a very desirable tolerability profile, 5a (branebrutinib, BMS-986195) has advanced into clinical studies.
