Background Information
ZNF638 (Zinc finger protein 638) is also named as NP220 and ZFML. ZNF638 is a newly discovered member of zinc finger protein family for adipocyte function in vitro. And ZNF638regulates triglyceride metabolism via ANGPTL8 in an estrogen dependent manner (PMID: 38211696). ZNF638 plays a role as a transcriptional coregulator of adipocyte differentiation via induction of PPARγ in cooperation with CCAAT/enhancer binding proteins (C/EBPs) (PMID: 25024404). ZNF638 is localized in nuclear bodies enriched with splicing factors (PMID: 25024404). The ZNF638 protein is modified and exhibits a molecular weight of ~300 kDa (PMID: 33040080)

What customers say
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Moritz (Verified Customer) (09-26-2025) | Several band are visible in the area between 150-250 kDa
 |
Aleksandr (Verified Customer) (07-29-2025) | Antibody recognise a band of the expected size with some other prominent, likely non-specific ones
 |
Tsimafei (Verified Customer) (08-07-2024) | Great antibody
 |
Julia (Verified Customer) (08-07-2024) | Band below 250 kDa marker is likely the Znf639 (~221kDa), there is also strong signal between 100-50kDa. I used 30ug of mESC protein extract.
