 154-249 4.60e-69

second type I K homology (KH) RNA-binding domain found in partner of NOB1 (PNO1) and similar proteins; PNO1 is an RNA-binding protein that acts as a ribosome assembly factor and plays an important role in ribosome biogenesis. It positively regulates dimethylation of two adjacent adenosines in the loop of a conserved hairpin near the 3'-end of 18S rRNA. PNO1 contains two K-homology (KH) RNA-binding domains. The model corresponds to the second one.

 156-238 1.16e-10

second type I K homology (KH) RNA-binding domain found in Pyrococcus horikoshii Dim2p and similar proteins; The family includes a group of conserved KH domain-containing protein mainly from archaea, such as Dim2p homologues from Pyrococcus horikoshii and Aeropyrum pernix. Dim2p acts as a preribosomal RNA processing factor that has been identified as an essential protein for the maturation of 40S ribosomal subunit in Saccharomyces cerevisiae. It is required for the cleavage at processing site A2 to generate the pre-20S rRNA and for the dimethylation of the 18S rRNA by 18S rRNA dimethyltransferase, Dim1p. Dim2p contains two K-homology (KH) RNA-binding domains. The model corresponds to the second one.

 177-225 5.14e-05

fourth type I K homology (KH) RNA-binding domain found in the insulin-like growth factor 2 mRNA-binding protein (IGF2BP) family; The IGF2BP family includes three members: IGF2BP1/IMP-1/CRD-BP/VICKZ1, IGF2BP2/IMP-2/VICKZ2, and IGF2BP3/IMP-3/VICKZ3, which are RNA-binding factors that recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). They function by binding to the 5' UTR of the insulin-like growth factor 2 (IGF2) mRNA and regulating IGF2 translation. IGF2BP proteins contain four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the fourth one.

K homology (KH) RNA-binding domain, type I; KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but they share a single KH motif. The KH motif is folded into a beta alpha alpha beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension and type I KH domains (e.g. hnRNP K) contain a C-terminal extension. Some KH-I superfamily members contain a divergent KH domain that lacks the RNA-binding GXXG motif. Some others have a mutated GXXG motif which may or may not have nucleic acid binding ability.
