Non-receptor tyrosine kinase which mediates signal transduction downstream of a variety of transmembrane receptors including classical immunoreceptors like the B-cell receptor (BCR). Regulates several biological processes including innate and adaptive immunity, cell adhesion, osteoclast maturation, platelet activation and vascular development (PubMed:12387735, PubMed:33782605). Assembles into signaling complexes with activated receptors at the plasma membrane via interaction between its SH2 domains and the receptor tyrosine-phosphorylated ITAM domains. The association with the receptor can also be indirect and mediated by adapter proteins containing ITAM or partial hemITAM domains. The phosphorylation of the ITAM domains is generally mediated by SRC subfamily kinases upon engagement of the receptor. More rarely signal transduction via SYK could be ITAM-independent. Direct downstream effectors phosphorylated by SYK include DEPTOR, VAV1, PLCG1, PI-3-kinase, LCP2 and BLNK (PubMed:12456653, PubMed:15388330, PubMed:34634301, PubMed:8657103). Initially identified as essential in B-cell receptor (BCR) signaling, it is necessary for the maturation of B-cells most probably at the pro-B to pre-B transition (PubMed:12456653). Activated upon BCR engagement, it phosphorylates and activates BLNK an adapter linking the activated BCR to downstream signaling adapters and effectors. It also phosphorylates and activates PLCG1 and the PKC signaling pathway. It also phosphorylates BTK and regulates its activity in B-cell antigen receptor (BCR)-coupled signaling. In addition to its function downstream of BCR also plays a role in T-cell receptor signaling. Plays also a crucial role in the innate immune response to fungal, bacterial and viral pathogens. It is for instance activated by the membrane lectin CLEC7A. Upon stimulation by fungal proteins, CLEC7A together with SYK activates immune cells inducing the production of ROS. Also activates the inflammasome and NF-kappa-B-mediated transcription of chemokines and cytokines in presence of pathogens. Regulates neutrophil degranulation and phagocytosis through activation of the MAPK signaling cascade (By similarity). Required for the stimulation of neutrophil phagocytosis by IL15 (PubMed:15123770). Also mediates the activation of dendritic cells by cell necrosis stimuli. Also involved in mast cells activation. Involved in interleukin-3/IL3-mediated signaling pathway in basophils (By similarity). Also functions downstream of receptors mediating cell adhesion (PubMed:12387735). Relays for instance, integrin-mediated neutrophils and macrophages activation and P-selectin receptor/SELPG-mediated recruitment of leukocytes to inflammatory loci. Also plays a role in non-immune processes. It is for instance involved in vascular development where it may regulate blood and lymphatic vascular separation. It is also required for osteoclast development and function. Functions in the activation of platelets by collagen, mediating PLCG2 phosphorylation and activation. May be coupled to the collagen receptor by the ITAM domain-containing FCER1G. Also activated by the membrane lectin CLEC1B that is required for activation of platelets by PDPN/podoplanin. Involved in platelet adhesion being activated by ITGB3 engaged by fibrinogen. Together with CEACAM20, enhances production of the cytokine CXCL8/IL-8 via the NFKB pathway and may thus have a role in the intestinal immune response (By similarity).

Spleen tyrosine kinase commonly known as Syk is a non-receptor tyrosine kinase with a mass of about 72 kDa. It serves as a critical signaling molecule in immune cells. Syk is expressed in various cell types such as B cells T cells monocytes and others involved in the immune response. It initiates signaling cascades by binding to immunoreceptor tyrosine-based activation motifs (ITAMs). Alternate forms include phosphorylated Syk often referred to as p-Syk which activates various downstream signaling pathways.
Syk plays a role in transmitting signals from the cell surface to the interior of the cell facilitating various cellular activities. It is a part of signal transduction complexes and functions in the regulation of immune cell activation differentiation and survival. It affects processes like Fc receptor signaling in macrophages and neutrophils impacting immune responses and inflammation. The phospho-Syk form influences the strength and duration of signaling affecting various cellular functions.
Syk is significant in the B-cell receptor (BCR) signaling pathway and Fc receptor signaling pathway. Within these pathways Syk interacts with proteins like Lyn and Fyn which are other kinases involved in BCR signal transduction. Syk phosphorylation noted as p-Syk plays a part in activating downstream molecules such as phospholipase C gamma (PLCγ) to mediate cellular responses to external stimuli. The critical role of Syk in these pathways influences both adaptive and innate immune responses.
Syk correlates with conditions like rheumatoid arthritis and certain B-cell lymphomas. In rheumatoid arthritis aberrant Syk signaling contributes to the inflammation and joint destruction characteristic of the disease. Syk's role in B-cell antigen receptor signaling links it to B-cell lymphomas where dysregulation in signaling pathways leads to uncontrolled proliferation of malignant B cells. The involvement of Syk in both disease contexts suggests its potential as a therapeutic target along with pathways related to proteins like BLNK and PLCγ in these disorders.
