• Synonyms: ACK1; ACK1 Antibody (Center Y284) Blocking peptide; Activated CDC42 kinase 1; ACK-1; Tyrosine kinase non-receptor protein 2; TNK2; TNK2 blocking peptide

• Specificity: The synthetic peptide sequence used to generate the antibody was selected from the Center Y284 region of ACK1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
• Form/Format: Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.
• Sequence Length: 1038

• Cellular Location: Cell membrane. Nucleus. Endosome. Cell junction, adherens junction. Cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side Cytoplasmic vesicle, clathrin-coated vesicle. Membrane, clathrin- coated pit. Note: The Tyr-284 phosphorylated form is found both in the membrane and nucleus. Colocalizes with EGFR on endosomes Nuclear translocation is CDC42-dependent
• Tissue Location: The Tyr-284 phosphorylated form shows a significant increase in expression in breast cancers during the progressive stages i.e. normal to hyperplasia (ADH), ductal carcinoma in situ (DCIS), invasive ductal carcinoma (IDC) and lymph node metastatic (LNMM) stages. It also shows a significant increase in expression in prostate cancers during the progressive stages.
• Preparation and Storage: Maintain refrigerated at 2-8 degree C for up to 6 months. For long term storage store at -20 degree C.

Related Product Information for TNK2 blocking peptide

Non-receptor tyrosine-protein and serine/threonine- protein kinase that is implicated in cell spreading and migration, cell survival, cell growth and proliferation. Transduces extracellular signals to cytosolic and nuclear effectors. Phosphorylates AKT1, AR, MCF2, WASL and WWOX. Implicated in trafficking and clathrin-mediated endocytosis through binding to epidermal growth factor receptor (EGFR) and clathrin. Binds to both poly- and mono-ubiquitin and regulates ligand-induced degradation of EGFR, thereby contributing to the accumulation of EGFR at the limiting membrane of early endosomes. Downstream effector of CDC42 which mediates CDC42-dependent cell migration via phosphorylation of BCAR1. May be involved both in adult synaptic function and plasticity and in brain development. Activates AKT1 by phosphorylating it on 'Tyr-176'. Phosphorylates AR on 'Tyr-267' and 'Tyr-363' thereby promoting its recruitment to androgen-responsive enhancers (AREs). Phosphorylates WWOX on 'Tyr- 287'. Phosphorylates MCF2, thereby enhancing its activity as a guanine nucleotide exchange factor (GEF) toward Rho family proteins. Contributes to the control of AXL receptor levels. Confers metastatic properties on cancer cells and promotes tumor growth by negatively regulating tumor suppressor such as WWOX and positively regulating pro-survival factors such as AKT1 and AR.

NCBI Description

This gene encodes a tyrosine kinase that binds Cdc42Hs in its GTP-bound form and inhibits both the intrinsic and GTPase-activating protein (GAP)-stimulated GTPase activity of Cdc42Hs. This binding is mediated by a unique sequence of 47 amino acids C-terminal to an SH3 domain. The protein may be involved in a regulatory mechanism that sustains the GTP-bound active form of Cdc42Hs and which is directly linked to a tyrosine phosphorylation signal transduction pathway. Several alternatively spliced transcript variants have been identified from this gene, but the full-length nature of only two transcript variants has been determined. [provided by RefSeq, Jul 2008]
