Rabbit Anti-B-Raf/FITC Conjugated antibody
background:
The Raf kinases are important intermediates in signal transduction. Raf protein family members, including A Raf and B Raf, have intrinsic serine/threonine kinase activity. Interaction between Ras proteins and Raf proteins results in Raf-mediated phosphorylation and activation of MEK (also known as MAP kinase kinase). Defects in BRAF are involved in a wide range of cancers. B-Raf is a serine/threonine protein kinase that acts as a signal transducer from membrane-associated receptors to nuclear transcription factors. 1 BRAF is important for the regulation of cell proliferation and determination of cell fate during embryogenesis. BRAF acts downstream of Ras and upstream of MEK in the Ras-Raf-MEK-ERK signal transduction pathway, which is a conserved RAS-activated protein kinase cascade that regulates cell growth, proliferation, and differentiation in response to growth factors, cytokines, and hormones.
Subunit:
Monomer. Homodimer. Heterodimerizes with RAF1, and the heterodimer possesses a highly increased kinase activity compared to the respective homodimers or monomers. Heterodimerization is mitogen-regulated and enhanced by 14-3-3 proteins. MAPK1/ERK2 activation can induce a negative feedback that promotes the dissociation of the heterodimer by phosphorylating BRAF at Thr-753. Found in a complex with at least BRAF, HRAS1, MAP2K1, MAPK3 and RGS14. Interacts with RIT1. Interacts (via N-terminus) with RGS14 (via RBD domains); the interaction mediates the formation of a ternary complex with RAF1, a ternary complex inhibited by GNAI1. Interacts with DGKH.
Subcellular Location:
Nucleus. Cytoplasm. Cell membrane.
Tissue Specificity:
Brain and testis.
Similarity:
Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. RAF subfamily.
Contains 1 phorbol-ester/DAG-type zinc finger.
Contains 1 protein kinase domain.
Contains 1 RBD (Ras-binding) domain.

BRAF蛋白是有丝分裂原活化的蛋白激酶/细胞外信号调节激酶途径蛋白。正常的B-Raf蛋白的功能是传递来自细胞膜的信号,在Ras-Raf-MEK-ERK信号转导调节途径中有着重要的作用.
BRAF是在癌细胞的生长和存活中起到关键作用的蛋白质,并且在大多数恶性黑素瘤患者和少数结肠癌、乳腺癌和肺癌患者中发生突变,目前BRAF也用于恶性黑素瘤和肿瘤的研究。
