Zinc finger present in dystrophin, CBP/p300. ZZ in dystrophin binds calmodulin. Putative zinc finger; binding not yet shown. Four to six cysteine residues in its sequence are responsible for coordinating zinc ions, to reinforce the structure [2].
This family consists of several drought induced 19 (Di19) like proteins. Di19 has been found to be strongly expressed in both the roots and leaves of Arabidopsis thaliana during progressive drought [1]. This domain is a zinc-binding domain.

This entry represents the N-terminal of E3 ubiquitin-protein ligases UBR4 (POE or PUSHOVER in Drosophila), which are components of the N-rule pathway, identified as noncanonical N-recognins implicated in bulk lysosomal degradation and autophagy. These are extraordinarily large proteins that recognise and bind to proteins with N-terminal destabilising residues according to the N-end rule leading them to their ubiquitination and degradation. These proteins share a UBR box (Pfam:PF02207) with others E3-ligases UBR box proteins but UBR4 lacks the ubiquitylation domain, suggesting that it may interact with other catalytic proteins [1,2,3].
