This family includes the previously defined UBA and TS-N domains. The UBA-domain (ubiquitin associated domain) is a novel sequence motif found in several proteins having connections to ubiquitin and the ubiquitination pathway. The structure of the UBA domain consists of a compact three helix bundle [1]. This domain is found at the N terminus of EF-TS hence the name TS-N. The structure of EF-TS is known and this domain is implicated in its interaction with EF-TU [2]. The domain has been found in non EF-TS proteins such as alpha-NAC Swiss:P70670 and MJ0280 Swiss:Q57728 [1].	Domain
B [auth X]	PF09280	XPC-binding domain (XPC-binding)	XPC-binding domain	Members of this family adopt a structure consisting of four alpha helices, arranged in an array. They bind specifically and directly to the xeroderma pigmentosum group C protein (XPC) to initiate nucleotide excision repair [1].	Domain
