Rabbit anti-Human CENPB Polyclonal Antibody

Uniprot Id

P07199

Target Species

Human

Target Name

CENPB

Target Full Name

Major centromere autoantigen B

Target Function

Interacts with centromeric heterochromatin in chromosomes and binds to a specific 17 bp subset of alphoid satellite DNA, called the CENP-B box. May organize arrays of centromere satellite DNA into a higher-order structure which then directs centromere formation and kinetochore assembly in mammalian chromosomes (Probable).

Target Subcellular Location

Nucleus. Chromosome, centromere.

Target Research Area

Epigenetics and Nuclear Signaling

Target Synonyms

CENP B; CENP-B; CENPB; CENPB_HUMAN; centromere autoantigen B; Centromere protein B; Centromere protein B; 80kDa; Major centromere autoantigen B

Target Background

This gene product is a highly conserved protein that facilitates centromere formation. It is a DNA-binding protein that is derived from transposases of the pogo DNA transposon family. It contains a helix-loop-helix DNA binding motif at the N-terminus, and a dimerization domain at the C-terminus. The DNA binding domain recognizes and binds a 17-bp sequence (CENP-B box) in the centromeric alpha satellite DNA. This protein is proposed to play an important role in the assembly of specific centromere structures in interphase nuclei and on mitotic chromosomes. It is also considered a major centromere autoantigen recognized by sera from patients with anti-centromere antibodies.
