Th-Pok Antibody / ZBTB7B

TH-POK (T-helper-inducing POZ/Kr ppel-like factor), also known as zinc finger protein 67 (ZFP67), zinc finger and BTB domain-containing protein 7B or Kr ppel-related zinc finger protein cKrox, is a 539 amino acid protein that contains one BTB (POZ) domain and four C2H2-type zinc fingers. Localized to the nucleus, TH-POK functions primarily as a key regulator of lineage commitment of immature T-cell precursors. Specifically, the presence of TH-POK directs positively selected thymocytes to the CD4 lineage, whereas its absence causes default development to the CD8 lineage. TH-POK also functions as a transcriptional repressor of various other genes, such as COL1A1, COL1A2 and Fibronectin.
