This gene encodes a SCAN box domain-containing protein. The SCAN domain is a highly conserved, leucine-rich motif of approximately 60 aa originally found within a subfamily of zinc finger proteins.
SCAND1 is a SCAN family protein that lacks the zinc finger region. Heterodimerization between different members of the SCAN protein family probably allows them to control the expression of a larger number of genes and the identification of the NY-REN21-SCAND1 interaction may help understand the mechanism of action of the multi-finger transcription factors.
