General annotation (Comments)

Function

Involved with pre-mRNA processing. Forms complexes (ribonucleosomes) with at least 20 other different hnRNP and heterogeneous nuclear RNA in the nucleus.

Subunit structure

Identified in the spliceosome C complex. Identified in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, NCL, PABPC1, PABPC4, PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, YBX1 and untranslated mRNAs. Interacts with IGF2BP1. Ref.11 Ref.14

Subcellular location

Nucleusnucleoplasm. Cytoplasm. Note: Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Component of ribonucleosomes. Predominantly nucleoplasmic, however isoform A2 is also found in the cytoplasm of cells in some tissues. Not found in the nucleolus. Ref.14

Sequence similarities

Contains 2 RRM (RNA recognition motif) domains.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform B1 (identifier: P22626-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform A2 (identifier: P22626-2)

The sequence of this isoform differs from the canonical sequence as follows:
     3-14: Missing.
