CC   -!- FUNCTION: Non-receptor tyrosine kinase involved in various processes
CC       such as cell growth, development, differentiation or histone
CC       modifications. Mediates essential signaling events in both innate and
CC       adaptive immunity. In the cytoplasm, plays a pivotal role in signal
CC       transduction via its association with type I receptors such as growth
CC       hormone (GHR), prolactin (PRLR), leptin (LEPR), erythropoietin (EPOR),
CC       thrombopoietin (THPO); or type II receptors including IFN-alpha, IFN-
CC       beta, IFN-gamma and multiple interleukins. Following ligand-binding to
CC       cell surface receptors, phosphorylates specific tyrosine residues on
CC       the cytoplasmic tails of the receptor, creating docking sites for STATs
CC       proteins. Subsequently, phosphorylates the STATs proteins once they are
CC       recruited to the receptor. Phosphorylated STATs then form homodimer or
CC       heterodimers and translocate to the nucleus to activate gene
CC       transcription. For example, cell stimulation with erythropoietin (EPO)
CC       during erythropoiesis leads to JAK2 autophosphorylation, activation,
CC       and its association with erythropoietin receptor (EPOR) that becomes
CC       phosphorylated in its cytoplasmic domain. Then, STAT5 (STAT5A or
CC       STAT5B) is recruited, phosphorylated and activated by JAK2. Once
CC       activated, dimerized STAT5 translocates into the nucleus and promotes
CC       the transcription of several essential genes involved in the modulation
CC       of erythropoiesis. Part of a signaling cascade that is activated by
CC       increased cellular retinol and that leads to the activation of STAT5
CC       (STAT5A or STAT5B). In addition, JAK2 mediates angiotensin-2-induced
CC       ARHGEF1 phosphorylation. Plays a role in cell cycle by phosphorylating
CC       CDKN1B. Cooperates with TEC through reciprocal phosphorylation to
CC       mediate cytokine-driven activation of FOS transcription. In the
CC       nucleus, plays a key role in chromatin by specifically mediating
CC       phosphorylation of 'Tyr-41' of histone H3 (H3Y41ph), a specific tag
CC       that promotes exclusion of CBX5 (HP1 alpha) from chromatin.

CC   -!- PTM: Undergoes Notch-induced ubiquitination and subsequent proteasomal
CC       degradation which is mediated by ASB1 or ASB2, the substrate-
CC       recognition components of probable ECS E3 ubiquitin-protein ligase
CC       complexes. {ECO:0000250|UniProtKB:O60674}.
CC   -!- DISRUPTION PHENOTYPE: Embryos are anemic and die around day 12.5 post-
CC       coitum (dpc). Primitive erythrocytes are found, but definitive
CC       erythropoiesis is absent. Fetal liver myeloid progenitors, although
CC       present based on the expression of lineage specific markers, fail to
CC       respond to erythropoietin (Epo), thrombopoietin (Thpo), interleukin-3
CC       (Il3), or granulocyte and macrophage colony-stimulating factor 1 (Csf1
CC       and Csf2). Fetal liver BFU-E and CFU-E colonies are completely absent.
CC       However, multilineage hematopoietic stem cells (CD34(low), c-kit(pos))
CC       can be found, and B-lymphopoiesis appears intact.
CC       {ECO:0000269|PubMed:9590173, ECO:0000269|PubMed:9590174}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC       kinase family. JAK subfamily. {ECO:0000255|PROSITE-ProRule:PRU00159}.
