  • 功能：
    p35 is a neuron specific activator of CDK5. The complex p35/CDK5 is required for neurite outgrowth and cortical lamination. Involved in dendritic spine morphogenesis by mediating the EFNA1-EPHA4 signaling. Activator of TPKII. The complex p35/CDK5 participates in the regulation of the circadian clock by modulating the function of CLOCK protein: phosphorylates CLOCK at 'Thr-451' and 'Thr-461' and regulates the transcriptional activity of the CLOCK-ARNTL/BMAL1 heterodimer in association with altered stability and subcellular distribution.
  • 基因功能参考文献：
    1. Study demonstrated that NEAT1 and HOTAIR negatively regulate CDK5R1 mRNA levels, while MALAT1 has a positive effect. PMID: 29997370
    2. the downregulation of the miR-15/107 family might have a role in the pathogenesis of AD by increasing the levels of CDK5R1/p35 and consequently enhancing CDK5 activity. PMID: 27343180
    3. It is shown that p5 binds the kinase at the same CDK5/p25 and CDK5/p35 interfaces, and is thus a non-selective competitor of both activators, in agreement with available experimental data in vitro. PMID: 27387995
    4. the minor allele of CDK5R1 3'-UTR rs735555 polymorphism was associated with increased risk for NS-ID. In conclusion, our data suggest that mutations and polymorphisms in CDK5 and CDK5R1 genes may contribute to the onset of the NS-ID phenotype PMID: 26657932
    5. Under cell-free in vitro conditions, p35 is covalently modified by SUMO1. SUMO2 is conjugated to p35 in cells. The 2 major SUMO acceptor lysines in p35 are K246 and K290. Different degrees of oxidative stress resulted in differential p35 sumoylation. PMID: 25391294
