General description
Centromere protein T (UniProt Q96BT3; also known as CENP-T, Interphase centromere complex protein 22) is encoded by the CENPT (also known as C16orf56, ICEN22) gene (Gene ID 80152) in human. Kinetochore complex-mediated chromosome interaction with microtubules from the mitotic spindle is essential for proper chromosome segregation during mitosis. The kinetochore is a macromolecular structure composed of almost 100 different proteins assembled upon the centromere in a cell cycle-regulated manner. CENP-T and 15 other chromatin proximal proteins constitute the Constitutive Centromere Associated Network (CCAN) present at centromeres throughout the cell cycle. Some CCAN proteins (e.g. CENPT/W complex and CENP-C) mediate DNA binding, while others (e.g. CENP-N) interact directly with CENP-A-containing nucleosomes. Evidence suggests that CENP-C and the CENP-T/W complex function as core kinetochore assembly factors in vertebrate cells.
Specificity
Specifically reacts with the immunogen peptide, but not the corresponding non-phosphorylated sequence, by dot blot analysis.
Immunogen
Epitope: CENP-T pSer47
Linear peptide corresponding to a human CENP-T sequence containing phosphorylated Ser47.
Application
Anti-phospho CENP-T (Ser47) Antibody is an antibody against phospho CENP-T for use in Immunocytochemistry, Dot Blot, Western Blotting.
Immunocytochemistry Analysis: 4.0 µg/mL from a representative lot detected phospho CENP-T (Ser47) in HUVEC and A431 cells.
Dot Blot Analysis: 1.0 µg/mL from a representative lot detected the immunogen peptide, but not the corresponding non-phosphorylated sequence, by dot blot analysis.
Immunocytochemistry Analysis: A representative lot detected a closely synchronized CENP-T pSer47 phosphorylation and Hec1 immunoreactivity at the centromeres throughout HeLa cell cycle, starting at Telo/G1 and peaking at metaphase, followed by a steady deline of ~80% toward anaphase (Gascoigne, K.E., et al. (2011). Cell. 145(3):410-422).
Western Blotting Analysis: A representative lot detected the in vitro phosphorylation of recombinant CENP-T on Ser47 by recombinant CDK2/cyclin A (Gascoigne, K.E., et al. (2011). Cell. 145(3):410-422).

Defects in chromosome-microtubule attachment can cause chromosomal instability (CIN), frequently associated with infertility and aggressive cancers. Chromosome-microtubule attachment is mediated by a large macromolecular structure, the kinetochore. Sister kinetochores of each chromosome are pulled by microtubules from opposing spindle-poles, a
