In molecular biology, the UBX protein domain is found in ubiquitin-regulatory proteins, which are members of the ubiquitination pathway, as well as a number of other ubiquitin-like proteins including FAF-1 (FAS-associated factor 1), the human Rep-8 reproduction protein and several hypothetical proteins from yeast. The function of the UBX domain is not known although the fragment of avian FAF-1 containing the UBX domain causes apoptosis of transfected cells.

Function

So far, as yet, no general function for the UBX domain has yet emerged. [1] Additionally, the absence of a carboxy-terminal di- glycine motif, however, indicates that UBX domains are not covalently attached to target proteins in a ubiquitin-like manner. [2]

Structure

The UBX domain comprises about 80 amino acid residues. They are distinct structural units defining a large family of proteins that often exhibit a modular domain architecture three-dimensional structures of UBX domains reveal a close structural relationship with ubiquitin despite the lack of significant sequence homology [2]

Homology

UBX domain is very similar to ubiquitin which gives us some indication of evolution. There are ubiquitin fusion which seem to be advantageous for ribosomal subunit folding. [2]
