A	PF10996	Beta-Casp domain (Beta-Casp)	Beta-Casp domain	The beta-CASP domain is found C terminal to the beta-lactamase domain in pre-mRNA 3'-end-processing endonuclease. The active site of this enzyme is located at the interface of these two domains [1].	Domain
B	PF08783	DWNN domain (DWNN)	DWNN domain	DWNN is a ubiquitin like domain found at the N terminus of the RBBP6 family of splicing-associated proteins [1]. The DWNN domain is independently expressed in higher vertebrates so it may function as a novel ubiquitin-like modifier of other proteins ...
