Fast track antibodies constitute a diverse group of products that have been released to accelerate your research, but are not yet fully characterized. They have all been affinity purified and show high titre values against the immunizing peptide (by ELISA).
Use at an assay dependent concentration. This antibody gave a positive result in ELISA against the immunizing peptide (ab33028).
Not yet tested in other applications.
FunctionTranscriptional repressor. May act as a tumor suppressor. May be involved in development of head, face, limbs and ventral body wall.
Tissue specificityUbiquitously expressed with highest levels found in lung, colon, prostate, thymus, testis and ovary. Expression is absent or decreased in many tumor cells.
Sequence similaritiesBelongs to the krueppel C2H2-type zinc-finger protein family. Hic subfamily. Contains 1 BTB (POZ) domain. Contains 5 C2H2-type zinc fingers.
Post-translational modificationsAcetylated on several residues, including Lys-333. Lys-333 is deacetylated by SIRT1. Sumoylated on Lys-333 by a PIAS family member, which positively regulates transcriptional repression ativity and is enhanced by HDAC4.
