B	PF22891	Eukaryotic type KH-domain (KH-domain type I) (327.11.2) (KH_PNO1_2nd)	Eukaryotic type KH-domain (KH-domain type I) (327.11.2)	This entry represents the second KH domain found in the PNO1 protein. PNO1 is part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit.	Domain
B	PF00013	KH domain (KH_1)	KH domain	KH motifs bind RNA in vitro. Autoantibodies to Nova, a KH domain protein, cause paraneoplastic opsoclonus ataxia.	Domain
