General annotation (Comments)

Function

Splice factor regulating alternative splice site selection for certain mRNA precursors. Mediates regulation of pre-mRNA splicing in a PKA-dependent manner. Ref.8 Ref.10

Subunit structure

Monomer. Component of the spliceosome. Interacts with ZRANB2 and SFRS1/ASF through its Arg/Ser-rich domain. Interacts with RI and RII subunits of PKA. Ref.5 Ref.8 Ref.10

Subcellular location

Nucleus speckle Ref.8 Ref.10.

Tissue specificity

Widely expressed. Found in heart, brain, lung, liver, skeletal muscle, kidney and pancreas. Expressed in activated B-cells and placenta. Expressed in all cell lines tested including Jurkat-TAg, U-937 and HEK293 cells. Ref.10

Domain

RI-alpha binding site, predicted to form an amphipathic helix, could participate in protein-protein interactions with a complementary surface on the R-subunit dimer. Ref.10

Miscellaneous

The gene coding for this protein is located in the pseudoautosomal region 1 (PAR1) of X and Y chromosomes.

Sequence similarities

Contains 1 RRM (RNA recognition motif) domain.

Caution

Was originally (Ref.2) thought to be a cell surface protein involved in B-cell activation.

Sequence caution

The sequence AAA36187.1 differs from that shown. Reason: Frameshift at position 461.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q02040-1)

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: Q02040-2)

The sequence of this isoform differs from the canonical sequence as follows:
     385-385: A → L
     386-695: Missing.
Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.
Isoform 3 (identifier: Q02040-3)

The sequence of this isoform differs from the canonical sequence as follows:
     385-445: AVKLREQEQK...ERLLSILLSK → VGGSLCSRQP...EGVALVCRSR
     446-695: Missing.
Note: No experimental confirmation available.
