The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"SH3 Domains
".
FunFam 44: E3 ubiquitin-protein ligase MIB2, putative
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 8 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the
