 2-109 5.69e-52

type II K-homology (KH) RNA-binding domain found in 30S ribosomal protein S3 and similar proteins; 30S ribosomal protein S3, also called small ribosomal subunit protein uS3, is part of the head region of the 30S ribosomal subunit and binds to the lower part of the 30S subunit head. It may also bind mRNA in the 70S ribosome, positioning it for translation. S3 protein is believed to interact with mRNA as it threads its way from the latch into the channel. Members of this family contain only one canonical type II K-homology (KH) domain that has the signature motif GXXG (where X represents any amino acid).

Ribosomal protein S3, C-terminal domain; This family contains a central domain pfam00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.

 2-109 5.69e-52

type II K-homology (KH) RNA-binding domain found in 30S ribosomal protein S3 and similar proteins; 30S ribosomal protein S3, also called small ribosomal subunit protein uS3, is part of the head region of the 30S ribosomal subunit and binds to the lower part of the 30S subunit head. It may also bind mRNA in the 70S ribosome, positioning it for translation. S3 protein is believed to interact with mRNA as it threads its way from the latch into the channel. Members of this family contain only one canonical type II K-homology (KH) domain that has the signature motif GXXG (where X represents any amino acid).

 40-103 1.96e-08

type II K-homology (KH) RNA-binding domain superfamily; The K-homology (KH) domain binds single-stranded RNA or DNA, and 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 share a single "minimal KH motif" which 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 while type I KH domains (e.g. hnRNP K) contain a C-terminal extension, connected to the KH motif by variable loops that are different in different KH domains, whether they are type I or type II. KH-II superfamily members contain one or two KH domains, most of which are canonical type II KH domains that have the signature motif GXXG (where X represents any amino acid). The first KH domain found in archaeal cleavage and polyadenylation specificity factors (CPSFs) is a non-canonical type II KH domain that lacks the GXXG motif. Some others have mutated GXXG motifs which may or may not have nucleic acid binding ability.

 63-110 2.24e-03

first type I K homology (KH) RNA-binding domain found in poly(rC)-binding protein 1 (PCBP1) and similar proteins; The family includes PCBP1 (also called alpha-CP1, or heterogeneous nuclear ribonucleoprotein E1, or hnRNP E1, or nucleic acid-binding protein SUB2.3) and PCBP2 (also called alpha-CP2, or heterogeneous nuclear ribonucleoprotein E2, or hnRNP E2). They are single-stranded nucleic acid binding proteins that bind preferentially to oligo dC. They act as iron chaperones for ferritin. In case of infection by poliovirus, PCBP1 plays a role in initiation of viral RNA replication in concert with the viral protein 3CD. PCBP2 is a major cellular poly(rC)-binding protein. It also binds poly(rU). PCBP2 negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation. PCBP2 forms a metabolon with the heme oxygenase 1/cytochrome P450 reductase complex for heme catabolism and iron transfer. Both PCBP1 and PCBP2 contain three K-homology (KH) RNA-binding domains. The model corresponds to the first one.
