Domain

Ribosomal RNA-processing protein 14/surfeit locus protein 6, C-terminal domain (IPR029190)

Short name: Rrp14/SURF6_C

Domain relationships

None.

Description

This entry represents the C-terminal domain of the ribosomal RNA-processing protein 14 (Rrp14), which shares protein sequence similarity with surfeit locus protein 6 (SURF6).

In mammals, SURF6 is a component of the nucleolar matrix and has a strong binding capacity for nucleic acids [PMID: 9548374]. SURF6 is always found in the nucleolus regardless of the phase of the cell cycle suggesting that it is a structural protein constitutively present in nucleolar substructures. A role in rRNA processing has been proposed for this protein.

Saccharomyces cerevisiae member of the SURF-6 family, named Rrp14 (ribosomal RNA-processing protein 14), interacts with proteins involved in ribosomal biogenesis and cell polarity [PMID: 15629442]. It is required for the synthesis of both 40S and 60S ribosomal subunits and may also play some direct role in correct positioning of the mitotic spindle during mitosis [PMID: 17272295, PMID: 17804645].
