The protein encoded by this gene is a nucleoplasmic protein. It binds cytidine-rich sequences in double-stranded DNA. This protein has three types of domains: MH1, MH2 (repeated three times) and MH3. It is associated with packaging, transferring, or processing transcripts. Multiple alternatively spliced transcript variants have been found for this gene, but the biological validity of some variants has not been determined.ZNF638 (Zinc Finger Protein 638) is a Protein Coding gene. Diseases associated with ZNF638 include Cutaneous T Cell Lymphoma. Among its related pathways are Regulation of lipid metabolism by Peroxisome proliferator-activated receptor alpha (PPARalpha) and Developmental Biology. GO annotations related to this gene include nucleic acid binding and RNA binding.
