Invitrogen™ ZNF638 Polyclonal Antibody

Rabbit Polyclonal Antibody

Supplier:  Invitrogen™ PA537001

Catalog No. PIPA537001

Description

This antibody detects endogenous protein at a molecular weight of 220 kDa and 120 kDa (Isoform 5). Purity is >95% by SDS-PAGE.

Zinc-finger proteins contain DNA-binding domains and have a wide variety of functions, most of which encompass some form of transcriptional activation or repression. NP220 (Nuclear protein 220), also designated Zinc finger protein 638 (ZNF638) or Cutaneous T-cell lymphoma-associated antigen se33-1, is a 1978 amino acid protein that contains one matrin-type zinc finger and two RRM (RNA recognition motif) domains, suggesting a role in transcriptional regulation. NP220 binds to double-stranded DNA fragments by recognizing clusters of cytidines. NP220 interacts with FHL-2 and is also thought to be phosphorylated by ATM or ATR upon DNA damage. It exists as five isoforms as a result of alternative splicing events. Isoform five of NP220 is a tumor-associated antigen found in several cutaneous T-cell lymphoma (CTCL), and in particular in mycosis fungoides patients and in Sezary syndrome patients.
