Tag Info

N-terminal His-tagged/Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Storage

Store at -20°C, for extended storage, conserve at -20°C or -80°C.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function(From Uniprot)

Serine/arginine-rich protein-specific kinase which specifically phosphorylates its substrates at serine residues located in regions rich in arginine/serine dipeptides, known as RS domains and is involved in the phosphorylation of SR splicing factors and the regulation of splicing. Promotes neuronal apoptosis by up-regulating cyclin-D1 (CCND1) expression. This is done by the phosphorylation of SRSF2, leading to the suppression of p53/TP53 phosphorylation thereby relieving the repressive effect of p53/TP53 on cyclin-D1 (CCND1) expression. Phosphorylates ACIN1, and redistributes it from the nuclear speckles to the nucleoplasm, resulting in cyclin A1 but not cyclin A2 up-regulation. Plays an essential role in spliceosomal B complex formation via the phosphorylation of DDX23/PRP28. Probably by phosphorylating DDX23, leads to the suppression of incorrect R-loops formed during transcription; R-loops are composed of a DNA:RNA hybrid and the associated non-template single-stranded DNA. Can mediate hepatitis B virus (HBV) core protein phosphorylation. Plays a negative role in the regulation of HBV replication through a mechanism not involving the phosphorylation of the core protein but by reducing the packaging efficiency of the pregenomic RNA (pgRNA) without affecting the formation of the viral core particles.

SRPK2 may play an important role in the progression and metastasis of prostate cancer. PMID:29587239
pausing of RNA polymerase II (RNA Pol II) initiates a signaling cascade whereby the serine/arginine protein kinase 2 (SRPK2) phosphorylates the DDX23 helicase, culminating in the suppression of R-loops. PMID:28076779
ten candidate variants were prioritised. Of these, SRPK2 (c.2044C>T[p.Arg682Trp]) and NOTCH1 (c.3835C>T[p.Arg1279Cys]), co-segregated with disease in the family; however, previous functional analyses on SRPK2 make this an unlikely candidate. Functional analyses in the variant (c.3835C>T[p.Arg1279Cys]) of the known CHD gene NOTCH1 demonstrated a non-significant decrease in signalling activity. PMID:27989580
Delta-secretase phosphorylation by SRPK2 plays a critical role in aggravating Alzheimer disease pathogenesis. PMID:28826672
In this study, it was found that the expression of SRPK2 was up-regulated in the clinical colon cancer samples. Overexpression of SRPK2 promoted the growth and migration of colon cancer cells, while knocking down the expression of SRPK2 inhibited the growth, migration and tumorigenecity of colon cancer cells.

SRPK2 knock down results in hypophosphorylation of the arginine-serine (RS) domain-containing human PRP28 protein (PRP28, also known as DDX23), and destabilizes PRP28 association with the tri-snRNP. PMID:18425142
overexpression of SRPK2 is associated with phosphorylating acinus and regulating its stimulatory effects on cyclin A1 expression, contributing to leukemia cell proliferation PMID:18559500
