CC -!- FUNCTION: Non-receptor tyrosine-protein kinase that transmits signals
CC from cell surface receptors and plays an important role in the
CC regulation of innate and adaptive immune responses, hematopoiesis,
CC responses to growth factors and cytokines, integrin signaling, but also
CC responses to DNA damage and genotoxic agents. Functions primarily as
CC negative regulator, but can also function as activator, depending on
CC the context. Required for the initiation of the B-cell response, but
CC also for its down-regulation and termination. Plays an important role
CC in the regulation of B-cell differentiation, proliferation, survival
CC and apoptosis, and is important for immune self-tolerance. Acts
CC downstream of several immune receptors, including the B-cell receptor,
CC CD79A, CD79B, CD5, CD19, CD22, FCER1, FCGR2, FCGR1A, TLR2 and TLR4.
CC Plays a role in the inflammatory response to bacterial
CC lipopolysaccharide. Mediates the responses to cytokines and growth
CC factors in hematopoietic progenitors, platelets, erythrocytes, and in
CC mature myeloid cells, such as dendritic cells, neutrophils and
CC eosinophils. Acts downstream of EPOR, KIT, MPL, the chemokine receptor
CC CXCR4, as well as the receptors for IL3, IL5 and CSF2. Plays an
CC important role in integrin signaling. Regulates cell proliferation,
CC survival, differentiation, migration, adhesion, degranulation, and
CC cytokine release. Down-regulates signaling pathways by phosphorylation
CC of immunoreceptor tyrosine-based inhibitory motifs (ITIM), that then
CC serve as binding sites for phosphatases, such as PTPN6/SHP-1,
CC PTPN11/SHP-2 and INPP5D/SHIP-1, that modulate signaling by
CC dephosphorylation of kinases and their substrates. Phosphorylates LIME1
CC in response to CD22 activation. Phosphorylates BTK, CBL, CD5, CD19,
CC CD72, CD79A, CD79B, CSF2RB, DOK1, HCLS1, LILRB3/PIR-B, MS4A2/FCER1B,
CC SYK and TEC. Promotes phosphorylation of SIRPA, PTPN6/SHP-1,
CC PTPN11/SHP-2 and INPP5D/SHIP-1. Required for rapid phosphorylation of
CC FER in response to FCER1 activation. Mediates KIT phosphorylation. Acts
CC as an effector of EPOR (erythropoietin receptor) in controlling KIT
CC expression and may play a role in erythroid differentiation during the
CC switch between proliferation and maturation. Depending on the context,
CC activates or inhibits several signaling cascades. Regulates
CC phosphatidylinositol 3-kinase activity and AKT1 activation. Regulates
CC activation of the MAP kinase signaling cascade, including activation of
CC MAP2K1/MEK1, MAPK1/ERK2, MAPK3/ERK1, MAPK8/JNK1 and MAPK9/JNK2.
CC Mediates activation of STAT5A and/or STAT5B (By similarity).
CC Phosphorylates LPXN on 'Tyr-72' (By similarity). Kinase activity
CC facilitates TLR4-TLR6 heterodimerization and signal initiation.
CC Phosphorylates SCIMP on 'Tyr-96'; this enhances binding of SCIMP to
CC TLR4, promoting the phosphorylation of TLR4, and a selective cytokine
CC response to lipopolysaccharide in macrophages (By similarity).
CC Phosphorylates CLNK (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P07948, ECO:0000250|UniProtKB:P25911}.

CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10028,
CC ECO:0000269|PubMed:9477973};
CC -!- ACTIVITY REGULATION: Subject to autoinhibition, mediated by
CC intramolecular interactions between the SH2 domain and the C-terminal
CC phosphotyrosine. Phosphorylation at Tyr-397 is required for optimal
CC activity. Phosphorylated by CSK at Tyr-508; phosphorylation at Tyr-508
CC inhibits kinase activity. Kinase activity is modulated by
CC dephosphorylation by PTPRC/CD45. {ECO:0000269|PubMed:9477973}.
CC -!- SUBUNIT: Interacts with TEC. Interacts (via SH2 domain) with FLT3
CC (tyrosine phosphorylated). Interacts with LIME1 and with CD79A upon
CC activation of the B-cell antigen receptor. Interacts with the B-cell
CC receptor complex. Interacts with phosphorylated THEMIS2. Interacts with
CC EPOR. Interacts with MS4A2/FCER1B. Interaction (via the SH2 and SH3
CC domains) with MUC1 is stimulated by IL7 and the subsequent
CC phosphorylation increases the binding between MUC1 and CTNNB1/beta-
CC catenin. Interacts with ADAM15. Interacts with NDFIP2 and more weakly
CC with NDFIP1. Interacts with FASLG. Interacts with KIT. Interacts with
CC HCLS1. Interacts with FCGR2B. Interacts with FCGR1A; the interaction
CC may be indirect. Interacts with CD19, CD22, CD79A and CD79B. Interacts
CC (via SH3 domain) with CBLC, PPP1R15A and PDE4A. Interacts with TGFB1I1.
CC Interacts (via SH3 domain) with PIK3R1, the regulatory subunit of
CC phosphatidylinositol 3-kinase; this interaction enhances
CC phosphatidylinositol 3-kinase activity. Interacts with CSF2RB, the
CC common subunit of the IL3, IL5 and CSF2 receptors. Interacts with PAG1;
CC identified in a complex with PAG1 and STAT3. Interacts with ABL1.
CC Interacts with PTPN6/SHP-1. Interacts (via SH3 domain) with SCIMP (via
CC proline-rich region) (By similarity). This interaction facilitates the
CC phosphorylation of SCIMP 'Tyr-96', which enhances binding of SCIMP to
CC TLR4, and consequently the phosphorylation of TLR4 in response to
CC stimulation by lipopolysaccharide in macrophages (By similarity).
CC Interacts with LPXN (via LD motif 3) and the interaction is induced
CC upon B-cell antigen receptor (BCR) activation. Interacts (via SH3-
CC domain) with ANKRD54 (via ankyrin repeat region) in an activation-
CC independent status of LYN. Forms a multiprotein complex with ANKRD54
CC and HCLS1 (By similarity). Interacts (via SH2 and SH3 domains) with
CC UNC119; leading to LYN activation (By similarity). Interacts with CD36.
CC Interacts with LYN (By similarity). Interacts with SKAP1 and FYB1; this
CC interaction promotes the phosphorylation of CLNK (By similarity).
