SRPK2 Protein, Human (Active, sf9, His-GST)
SRPK2 is a serine/arginine-rich protein-specific kinase that phosphorylates serine residues within the arginine/serine-rich domain (RS domain) and plays a critical role in regulating the splicing process effect. SRPK2 promotes neuronal apoptosis by upregulating cyclin-D1 (CCND1) expression and inhibiting the inhibitory effect of p53/TP53. SRPK2, Human (Active, sf9, His-GST) is the recombinant human-derived SRPK2 protein, expressed by Sf9 insect cells, with N-6*His;N-GST labeled tag.

Description
SRPK2 is a serine/arginine-rich protein-specific kinase that phosphorylates serine residues within the arginine/serine-rich domain (RS domain) and plays a critical role in regulating the splicing process effect. SRPK2 promotes neuronal apoptosis by upregulating cyclin-D1 (CCND1) expression and inhibiting the inhibitory effect of p53/TP53. SRPK2, Human (Active, sf9, His-GST) is the recombinant human-derived SRPK2 protein, expressed by Sf9 insect cells, with N-6*His;N-GST labeled tag.
Background
SRPK2, a serine/arginine-rich protein-specific kinase, exhibits a specific penchant for phosphorylating serine residues within arginine/serine-rich domains, known as RS domains. Functionally, SRPK2 is integral to the phosphorylation of SR splicing factors, intricately regulating splicing processes. Notably, SRPK2 contributes to neuronal apoptosis by up-regulating cyclin-D1 (CCND1) expression, achieved through the phosphorylation of SRSF2. This phosphorylation event suppresses p53/TP53 phosphorylation, thus alleviating p53/TP53's repressive impact on cyclin-D1 (CCND1) expression. Additionally, SRPK2 plays a crucial role in spliceosomal B complex formation by phosphorylating DDX23/PRP28, and its phosphorylation of ACIN1 leads to the redistribution of ACIN1 from nuclear speckles to the nucleoplasm, resulting in up-regulation of cyclin A1. Furthermore, SRPK2 participates in modulating hepatitis B virus (HBV) replication, impacting HBV core protein phosphorylation and pregenomic RNA (pgRNA) packaging efficiency, revealing its multifaceted regulatory roles in cellular and viral processes.
