Anti-BRSK1 antibody produced in rabbit

BRSK1 (BR serine/threonine kinase 1), also known as serine/threonine-protein kinase (SAD-1, SAD-B) and BRSK2 (SAD-A) belong to the family of Ser/Thr AMP-activated protein kinase (AMPK)-related kinases that are specifically expressed in the mammalian brain. BRSK1 gene is mapped to human chromosome 19q13.42. BRSK1 protein localizes in the synaptic vesicle in the hippocampus and cerebellum.

synthetic peptide corresponding to an internal sequence of human BRSK1, conjugated to KLH. The corresponding sequence is identical in mouse BRSK1.

Anti-BRSK1 antibody is suitable for use in western blot (2-4 μg/mL using S1 fraction extracts of mouse forebrain). The product can also be used for immunoprecipitation (10-20 μg) and indirect immunofluorescence (0.2-0.4 μg/mL) using HEK-293T cells overexpressing mouse BRSK1.

Anti-BRSK1 specifically recognizes mouse BRSK1.

BRSK1 (BR serine/threonine kinase 1) is essential for the polarization of cortical neurons. Knock-out mice that lack both BRSK1 and BRSK2 have defects in neuronal polarity and die prematurely after birth. Liver kinase B1(LKB1) phosphorylates and activates the serine/threonine-protein (SAD) kinases at a specific threonine residue within the T-loop activation segment of the kinase domain. BRSK1/2 in turn phosphorylates downstream effectors such as the microtubule-associated protein, tau and the cell cycle checkpoint kinase, Wee1-like protein kinase (Wee1). Phosphorylation of Wee1 by BRSK1/2 is required to regulate its activity and differentiation of polarized neurons. Also, BRSK1/SADB is localized to centrosomes and to control centrosome duplication. SADB phosphorylates γ-tubulin on Ser131 residue, suggesting that it controls centrosome homeostasis by regulating the phosphorylation of γ -tubulin.

BRSK1 is a serine/threonine kinase that facilitates the G(2)/M cell cycle arrest upon UV- or methyl methane sulfonate-induced DNA damage. This kinase also modulates the polarity of neurons and duplication of centrosomes. Anti-BRSK1 antibody is specific for mouse BRSK1. The antibody is also expected to react with human BRSK1. In immunoblotting, detection of the BRSK1 band is specifically inhibited by the BRSK1 immunizing peptide.

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
