ZSCAN21

ZSCAN21 (Zinc finger and SCAN domain-containing protein 21) is a human gene encoding a protein that belongs to the Krüppel-like zinc finger protein family. These proteins are characterized by the presence of multiple C2H2-type zinc finger domains, which are involved in DNA binding, and a SCAN (SRE-ZBP, CTfin51, AW-1, and Number 18 cDNA) domain, which mediates protein-protein interactions and is thought to contribute to transcriptional repression.

The precise function of ZSCAN21 is not fully understood, but its domain architecture suggests a role in transcriptional regulation. Zinc finger proteins are known to bind specific DNA sequences and regulate the expression of target genes. The SCAN domain often facilitates the formation of protein complexes, potentially allowing ZSCAN21 to interact with other regulatory proteins and influence gene expression in a context-dependent manner.

Research suggests ZSCAN21 may be involved in various cellular processes, including development and differentiation. Alterations in ZSCAN21 expression have been implicated in certain cancers, suggesting a possible role in tumorigenesis. Further research is needed to fully elucidate the specific biological functions of ZSCAN21 and its potential involvement in human diseases.

The ZSCAN21 gene is located on chromosome 16 in humans. Related genes within the ZSCAN family share similar domain structures and are often found in clusters within the genome, suggesting potential functional redundancy or coordinated regulation. The protein product of the ZSCAN21 gene is typically found in the nucleus, consistent with its proposed role in transcriptional regulation.
