Zinc Finger, B-Box Domain Containing Protein (ZBBX)

ZBBX, Contains 1 B box-type zinc finger. The B-box family represents a subgroup of Zn finger proteins that contain one or more B-box domains with specialized tertiary structures that are stabilized by binding Zn ions. As indicated above, the B-box domain is thought to be involved in protein–protein interactions. It is not yet known how B-box proteins function at the biochemical level, but they may be involved in modulating protein–protein interactions, such as those occurring in transcriptional complexes. Some of the B-box family members contain additional domains, but it remains to be seen if these regions of the protein confer additional discrete functions. In Arabidopsis, the B-box family consists of 32 proteins. The purpose of this letter is to establish a uniform terminology for the B-box proteins.
