Specificity/Sensitivity
PTK6/BRK (D4O2D) Rabbit mAb recognizes endogenous levels of total PTK6/BRK protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human PTK6/BRK protein.
Background
PTK6/BRK (protein-tyrosine kinase 6, Breast Tumor Kinase) is a non-receptor tyrosine kinase that is closely related to the FRK family of kinases and distantly related to SRC family kinases (1). PTK6/BRK possesses an N-terminal SRC homology 3 (SH3) domain that regulates kinase-substrate interactions, an auto-inhibitory SRC homology 2 (SH2) domain, and a carboxy-terminal kinase domain. Phosphorylation at Tyr342 in the activation loop of the kinase domain upregulates kinase activity, whereas phosphorylation at Tyr447 inhibits kinase activity (2). PTK6/BRK is expressed in differentiated epithelial cells in normal skin, gastrointestinal tract and colon, and its expression level is reportedly upregulated in some cancer cell types, including breast carcinoma, prostate cancer and colon cancer (3-5). Although typically localized in the nucleus of normal cells, PTK6/BRK has also been observed in the cytosol and plasma membrane in some contexts, notably during tumor progression, where it likely interacts with unique substrates. In the nucleus, PTK6/BRK functions to mediate signaling events important for differentiation and apoptosis (4); outside the nucleus, PTK6/BRK may function to relay upstream RTK signaling to downstream pathways via phosphorylation and activation of substrates such as paxillin, STAT and AKT, which in turn activate pathways to promote cell survival, invasion and migration. The upregulation, altered subcellular localization and associated signaling functions of PTK6/BRK in tumor cells make it a promising target for cancer therapy (6).
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

PTK6/BRK (D4O2D) Rabbit mAb
Western blot analysis of extracts from various cell lines using PTK6/BRK (D4O2D) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower).
Immunoprecipitation of PTK6/BRK protein from HCC1419 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is PTK6/BRK (D4O2D) Rabbit mAb. Western blot analysis was performed using PTK6/BRK (D4O2D) Rabbit mAb as primary antibody. Mouse Anti-rabbit IgG (conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 was used as the secondary antibody.
Confocal immunofluorescent analysis of HCC1419 (left, positive) and U-118 MG (right, negative) cells using PTK6/BRK (D4O2D) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
