The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterized, small proteins that may be involved in translation regulation [1]. The S4 domain probably mediates binding to RNA.
This family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.
This entry represents the first K homology (KH) domain found in NusA transcription termination factors. KH domains bind RNA and can function in RNA recognition [1]. NusA binds to RNA polymerase alpha subunit and promotes termination at certain RNA ha ...
This entry represents the first K homology (KH) domain found in NusA transcription termination factors. KH domains bind RNA and can function in RNA recognition [1]. NusA binds to RNA polymerase alpha subunit and promotes termination at certain RNA hairpin structures [2]. In prokaryotes, the N-terminal RNA polymerase-binding domain (NTD) is connected through a flexible hinge helix to three globular domains, the S1 and two K-homology (KH), KH1 and KH2. The KH domains of NusA belong to the type II KH RNA-binding domain superfamily [3].

The S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure.

The two eukaryotic subunits Rpb3 and Rpb11 dimerise to from a platform onto which the other subunits of the RNA polymerase assemble (D/L in archaea). The prokaryotic equivalent of the Rpb3/Rpb11 platform is the alpha-alpha dimer. The dimerisation domain of the alpha subunit/Rpb3 is interrupted by an insert domain (Pfam:PF01000). Some of the alpha subunits also contain iron-sulphur binding domains (Pfam:PF00037). Rpb11 is found as a continuous domain. Members of this family include: alpha subunit from eubacteria, alpha subunits from chloroplasts, Rpb3 subunits from eukaryotes, Rpb11 subunits from eukaryotes, RpoD subunits from archaeal spp, and RpoL subunits from archaeal spp.
Members of this family include: alpha subunit from eubacteria alpha subunits from chloroplasts Rpb3 subunits from eukaryotes RpoD subunits from archaeal
Ribosomal protein L25 is an RNA binding protein, that binds 5S rRNA. This family includes Ctc from B. subtilis Swiss:P14194, which is induced by stress.
Large ribosomal subunit protein uL24, C-terminal domain
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 m ...
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 makes very minor contributions to the biogenesis structure, and function of 60s ribosomal subunits [1]. However, RPL24 is essential to generate the first intermediate during 50s ribosomal subunits assembly [2]. RPL26 have an extra-ribosomal function to enhances p53 translation after DNA damage [3].
