Anti-phospho BAF60C (Ser247) from rabbit, purified by affinity chromatography

SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily D member 3 (UniProt: Q6STE5; also known as 60 kDa BRG-1/Brm-associated factor subunit C, BRG1-associated factor 60C, BAF60C) is encoded by the SMARCD3 (also known as BAF60C) gene (Gene ID: 6604) in human. BAF60C plays a key role in ATP dependent nucleosome remodeling by SMARCA4 containing complexes. Two isoforms of BAF60C have been reported that are produced by alternative splicing. Both isoforms are expressed in brain, heart, kidney, placenta, prostate, salivary glands, spleen, testis, thyroid, trachea, and uterus. However, isoform 1 is expressed also in skeletal muscle and adipose tissue. BAF60C belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex). During neural development a switch from a stem/progenitor to a post-mitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to post-mitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. BAF60C is also a component of nuclear Notch signaling and is required for the establishment of left-right asymmetry. Loss of BAF60C can lead to defects in the establishment of the left-right asymmetry cascade in mouse and zebrafish. It also serves a specific chromatin remodeling component for lipogenic gene transcription in liver. In response to insulin, it is phosphorylated at serine 247 by atypical PKC zeta//lambda, which causes translocation of BAF60C to the nucleus and allows a direct interaction of BAF60C with upstream stimulatory factor-1 (USF-1).
