Description

Description:

zinc finger protein 655 [Source:HGNC Symbol;Acc:HGNC:30899]

Entrez Summary

This gene encodes a zinc finger protein. The zinc finger proteins are involved in DNA binding and protein-protein interactions. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
