C [auth I]PF00240Ubiquitin family (ubiquitin)Ubiquitin familyThis family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260).

A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].

These proteins are activated in response to extracellular signals such as cytokines, growth factors and hormonal factors and translocate to the nucleus, where they bind to specific promoter sequences in target genes. This entry represents the all-helical linker domain that connects the DNA binding domain (Pfam:PF02864) and the SH2 domain (Pfam:PF00017) [1-5].

STATs share 6 structurally and functionally conserved domains including: an N-terminal domain (ND) that strengthens interactions between STAT dimers on adjacent DNA-binding sites; a coiled-coil STAT domain (CCD) that is implicated in protein-protein interactions; a DNA-binding domain (DBD) with an immunoglobulin-like fold similar to p53 tumour suppressor protein; an EF-hand-like linker domain connecting the DNA-binding and SH2 domains; an SH2 domain that acts as a phosphorylation-dependent switch to control receptor recognition and DNA-binding; and a C-terminal transactivation domain. This entry represents the coiled-coil domain (CCD)

This family represents the DNA binding domain of STAT, which has an ig-like fold. STAT proteins also include an SH2 domain Pfam:PF00017.
