This domain is found in Period circadian protein homolog 3 from Mus musculus (Per3) and similar proteins predominantly found in vertebrates. Per3 is involved in the day-time dependent (circadian) regulation of many physiological, behavioural, and biochemical processes. This entry represents the first PAS domain (PAS-A) present in this protein. This domain shows a five-stranded antiparallel beta- sheet covered on one face by alpha-helices [1-4].	Domain
A, B, C, D	PF08447	PAS fold (PAS_3)	PAS fold	The PAS fold corresponds to the structural domain that has previously been defined as PAS and PAC motifs [4]. The PAS fold appears in archaea, eubacteria and eukarya.	Domain
