General annotation (Comments)

Function

One of the major pre-mRNA-binding proteins. Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA.

Subunit structure

Interacts with RBM42 and ZIK1 By similarity. Identified in the spliceosome C complex, at least composed of AQR, ASCC3L1, C19orf29, CDC40, CDC5L, CRNKL1, DDX23, DDX41, DDX48, DDX5, DGCR14, DHX35, DHX38, DHX8, EFTUD2, FRG1, GPATC1, HNRPA1, HNRPA2B1, HNRPA3, HNRPC, HNRPF, HNRPH1, HNRNPK, HNRPM, HNRPR, HNRPU, KIAA1160, KIAA1604, LSM2, LSM3, MAGOH, MORG1, PABPC1, PLRG1, PNN, PPIE, PPIL1, PPIL3, PPWD1, PRPF19, PRPF4B, PRPF6, PRPF8, RALY, RBM22, RBM8A, RBMX, SART1, SF3A1, SF3A2, SF3A3, SF3B1, SF3B2, SF3B3, SFRS1, SKIV2L2, SNRPA1, SNRPB, SNRPB2, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF, SNRPG, SNW1, SRRM1, SRRM2, SYF2, SYNCRIP, TFIP11, THOC4, U2AF1, WDR57, XAB2 and ZCCHC8. Interacts with ANKRD28. Interacts with HCV core protein. Interacts with ASFV p30 protein.

Subcellular location

Cytoplasm. Nucleusnucleoplasm. Note: In case of ASFV infection, there is a shift in the localization which becomes predominantly nuclear. Ref.1

Post-translational modification

Arg-296 and Arg-299 are dimethylated, probably to asymmetric dimethylarginine. Ref.14

Sequence similarities

Contains 3 KH domains.

Mass spectrometry

Molecular mass is 50976.25 Da from positions 1 - 463 (P61978-1). Determined by MALDI. Ref.10

Binary interactions

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P61978-1)

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 2 (identifier: P61978-2)

The sequence of this isoform differs from the canonical sequence as follows:
     459-463: SGKFF → ADVEGF
Isoform 3 (identifier: P61978-3)

The sequence of this isoform differs from the canonical sequence as follows:
     111-134: Missing.
     459-463: SGKFF → ADVEGF
Note: No experimental confirmation available.
