A [auth D], B	PF17903	Krr1 KH1 domain (KH_KRR1_1st)	Krr1 KH1 domain	This entry represents the first KH domain in the KRR1 protein [1]. Krr1 is a ribosomal assembly factor. The KH1 domain is a divergent KH domain that lacks the RNA-binding GXXG motif and is involved in binding another assembly factor, Kri1 [1].	Domain
A [auth D], B	PF21800	KRR1 small subunit processome component, second KH domain (KH_KRR1_2nd)	KRR1 small subunit processome component, second KH domain	This is the second K homology domain (KH2) found in KRR1 small subunit processome component from the fungus Chaetomium thermophilum and similar eukaryotic sequences.	Domain
