|Protein Name||Tyrosine-protein kinase CSK|
|Molecular Weight||50704 MW|
|Protein Function||Non-receptor tyrosine-protein kinase that plays an important role in the regulation of cell growth, differentiation, migration and immune response. Phosphorylates tyrosine residues located in the C-terminal tails of Src-family kinases (SFKs) including LCK, SRC, HCK, FYN, LYN or YES1. Upon tail phosphorylation, Src-family members engage in intramolecular interactions between the phosphotyrosine tail and the SH2 domain that result in an inactive conformation. To inhibit SFKs, CSK is recruited to the plasma membrane via binding to transmembrane proteins or adapter proteins located near the plasma membrane. Suppresses signaling by various surface receptors, including T- cell receptor (TCR) and B-cell receptor (BCR) by phosphorylating and maintaining inactive several positive effectors such as FYN or LCK. .|
|Tissue Specificity||Expressed in lung and macrophages. .|
|Sequence Similarities||Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily.|
|Subcellular Localization||Cytoplasm . Cell membrane . Mainly cytoplasmic, also present in lipid rafts. .|
|Alternative Names||Tyrosine-protein kinase CSK;126.96.36.199;C-Src kinase;Protein-tyrosine kinase CYL;CSK;|
|Research Areas|||signal transduction|protein phosphorylation|tyrosine kinases|src family||

1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
