A, B	PF17849	Dis3-like cold-shock domain 2 (CSD2) (OB_Dis3)	Dis3-like cold-shock domain 2 (CSD2)	This domain has an OB fold and is found in the Dis3l2 protein [1]. This domain along with CSD1 binds to RNA.	Domain
A, B	PF00773	RNB domain (RNB)	RNB domain	This domain is the catalytic domain of ribonuclease II [1].	Domain
A, B	PF17877	DIS3-like exonuclease 2 C terminal (Dis3l2_C_term)	DIS3-like exonuclease 2 C terminal	This is the C-terminal S1 domain found in Dis3L2 proteins. Dis3L2 belongs to the RNase II/R 3-5 exonuclease superfamily, which includes the catalytic subunit of the RNA exosome in yeast and in humans [1].	Domain
