Overlay histogram showing Ramos cells stained with ab1881 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab1881, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2μg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Ramos cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Supplementary information

Fyn is a Src family tyrosine kinase with a molecular weight of approximately 59 kDa. It is often referred to as Fyn kinase and plays a significant role in signal transduction processes. This protein is observed in various tissues with high expression in the brain T cells and platelets. Fyn kinase is known for its function in cell communication and regulates different cellular processes in these tissues.
Biological function summary

Fyn kinase influences cell growth differentiation and survival. It is a part of larger signaling complexes including those accountable for the development and function of the central nervous system. The protein's activity is important for neural plasticity and supports synaptic communication particularly within the brain. Fyn can interact with other proteins in these complexes to help direct cellular responses to external signals.

Pathways

Fyn kinase is central to several intracellular signaling pathways such as the T cell receptor (TCR) signaling pathway and the integrin signaling pathway. The TCR signaling pathway involves the regulation of immune responses while the integrin signaling pathway contributes to cell adhesion and migration. Other proteins like Lck and Yes interact with Fyn within these pathways adding another layer of regulation and response in various cell types.

Fyn kinase has associations with Alzheimer's disease and certain types of cancer. In Alzheimer's dysregulation of Fyn activity contributes to synaptic dysfunction and neuronal damage. In cancer aberrant Fyn signaling can affect cellular proliferation and metastasis. Proteins such as Tau in Alzheimer's disease and Src in cancer relate to Fyn through their respective pathological processes.

Target data

Non-receptor tyrosine-protein kinase that plays a role in many biological processes including regulation of cell growth and survival, cell adhesion, integrin-mediated signaling, cytoskeletal remodeling, cell motility, immune response and axon guidance (PubMed : 11536198, PubMed : 15489916, PubMed : 15557120, PubMed : 16387660, PubMed : 20100835, PubMed : 7568038, PubMed : 7822789). Inactive FYN is phosphorylated on its C-terminal tail within the catalytic domain (PubMed : 15489916). Following activation by PKA, the protein subsequently associates with PTK2/FAK1, allowing PTK2/FAK1 phosphorylation, activation and targeting to focal adhesions (PubMed : 15489916). Involved in the regulation of cell adhesion and motility through phosphorylation of CTNNB1 (beta-catenin) and CTNND1 (delta-catenin) (PubMed : 17194753). Regulates cytoskeletal remodeling by phosphorylating several proteins including the actin regulator WAS and the microtubule-associated proteins MAP2 and MAPT (PubMed : 14707117, PubMed : 15536091). Promotes cell survival by phosphorylating AGAP2/PIKE-A and preventing its apoptotic cleavage (PubMed : 16841086). Participates in signal transduction pathways that regulate the integrity of the glomerular slit diaphragm (an essential part of the glomerular filter of the kidney) by phosphorylating several slit diaphragm components including NPHS1, KIRREL1 and TRPC6 (PubMed : 14761972, PubMed : 18258597, PubMed : 19179337). Plays a role in neural processes by phosphorylating DPYSL2, a multifunctional adapter protein within the central nervous system, ARHGAP32, a regulator for Rho family GTPases implicated in various neural functions, and SNCA, a small pre-synaptic protein (PubMed : 11162638, PubMed : 12788081, PubMed : 19652227). Involved in reelin signaling by mediating phosphorylation of DAB1 following reelin (RELN)-binding to its receptor (By similarity). Participates in the downstream signaling pathways that lead to T-cell differentiation and proliferation following T-cell receptor (TCR) stimulation (PubMed : 22080863). Phosphorylates PTK2B/PYK2 in response to T-cell receptor activation (PubMed : 20028775). Also participates in negative feedback regulation of TCR signaling through phosphorylation of PAG1 and PDCD1 (PubMed : 18056706, PubMed : 32184441). Phosphorylation of PAG1 promotes interaction between PAG1 and CSK and recruitment of CSK to lipid rafts (PubMed : 18056706). Phosphorylation of PDCD1 leads to the recruitment of PTPN11/SHP-2 that mediates dephosphorylation of key TCR proximal signaling molecules (PubMed : 32184441). CSK maintains LCK and FYN in an inactive form (By similarity). Promotes CD28-induced phosphorylation of VAV1 (PubMed : 11005864). In mast cells, phosphorylates CLNK after activation of immunoglobulin epsilon receptor signaling (By similarity). Can also promote CD244-mediated NK cell activation (PubMed : 15713798).
