Protein attributes

Sequence length	432 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Binds cAMP regulatory element DNA sequence. May play a role in RNA splicing. Ref.2
Subunit structure	May interact with SFRS1 and form homodimers. Interacts with JMJD6 and RBM25. Interacts with RSRC1 (via Arg/Ser-rich domain). Ref.7 Ref.8 Ref.10 Ref.14
Subcellular location	Nucleus speckle. Note: The subnuclear localization is affected by cisplatin. Ref.1 Ref.7
Tissue specificity	Widely expressed. Highest levels in heart, brain, pancreas, thymus, ovary, small intestine and peripheral blood leukocytes, as well as cerebellum, putamen and pituitary gland. Lowest levels in lung, liver and kidney. Also expressed in fetal tissues, including brain, heart, kidney, thymus and lung. Ref.1 Ref.2
Post-translational modification	Phosphorylated in vitro by SRPK1, SRPK2 and CLK1. Ref.7
Sequence similarities	Belongs to the Luc7 family.
Sequence caution	The sequence AAC79807.1 differs from that shown. Reason: Erroneous translation. Erroneous CDS prediction.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: O95232-1)

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: O95232-2)

The sequence of this isoform differs from the canonical sequence as follows:
     56-79: GPCEKIHDENLRKQYEKSSRFMKV → DVFGRGDNISDVSKFLEDDKWMEE
     80-432: Missing.

Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. No experimental confirmation available.
