Produktbeschreibung

Weitere Bezeichnung: Lck

Immunogen: Peptide corresponding to amino acids 22-36 in the sequence of human Lck.

Format: Purified

Isotyp: IgG1  (Passende Sekundärantikörper)

Klon: LCK-01

Beschreibung: Lck is a Src-family tyrosine kinase, which is essential for signaling through the T-cellreceptor (TCR) complex. Upon TCR triggering, Lck phosphorylates the ITAM motives in itszeta subunits, establishing binding sites for the SH2 domains of the tyrosine kinase ZAP70,which is also phosphorylated by Lck and thereby activated to generate subsequent signalingplatforms by phosphorylation of adaptor LAT. Whereas the majority of Lck is localized to theplasma membrane, there is also a significant fraction associated with the Golgi apparatus,which may contribute to Raf activation under conditions of weak stimulation through theTCR. Lck is also involved in the regulation of apoptosis induced by various stimuli, but notby the death receptors.

Spezifität: The antibody LCK-01 recognizes defined epitope (aa 22-36) of Lck, a 56 kDa Src-familyprotein tyrosine kinase. This antibody does not react with: Mouse.
