ZKSCAN5 (Zinc Finger with KRAB and SCAN Domains 5): ZKSCAN5 encodes a zinc finger protein containing KRAB (Krüppel-associated box) and SCAN (SRE-ZBP, CTfin51, AW-1, and Number 18 cDNA) domains. These domains play important roles in transcriptional regulation and DNA binding. The specific functions of ZKSCAN5 are still under investigation.
