    basic FUNCTION
  • not a casein kinase in vivo, likely involved in regulation of cell growth
  • may be involved in cell proliferation through GADD45GIP1 phosphorylation
  • role in cell proliferation and anchorage-independent cell growth
  • required for CADPS activity
  • novel enhancer of ACVRL1 signaling, and important regulator of ACVRL1 signaling and ACVRL1-mediated functions in endothelial cells
  • participates in PLK1-WEE1 complex formation interacting directly with WEE1 and thereby contributing to the regulation of G2-M cell cycle transition)
  • negative regulator of BMP signaling and osteoblast differentiation
  • might control neurotransmitter release by acting on SNARE proteins attached to cholesterol-enriched microdomains
  • crucial protein involved in the formation and clearance of aggresomes, and hence in cell viability in response to misfolded protein stress
  • participates in the regulation of fundamental cellular processes
  • CELLULAR PROCESS cell cycle, division
    cell life, proliferation/growth
    text insulin mediated cell metabolism and growth
    signaling signal transduction
    ubiquitous protein kinase which regulates metabolic pathways, signal transduction, transcription, translation, and replication
    a component
  • a heterotetramer (2A,2B) complexing with the FACT elongation transcription factor made of SSRP1 and FACTP140
    small molecule
  • GADD45GIP1
  • CSNK2A1
  • CSNK2A2
  • LYN
  • MBD4
  • RPL5
  • ZNF44
  • ZNHIT1
  • ACVRL1/CSNK2B interaction specifically enhanced Smad1/5/8 phosphorylation
  • interacting with TNFAIP1 (CSNK2B could phosphorylate TNFAIP1, which facilitated the distribution of TNFAIP1 in nucleus and enhanced its interaction with PCNA)
  • binding and regulatory partner for RPS6KA5
  • BMP receptor type Ia (BMPR1A) interacting protein
  • crucial modulator of HDAC6 activity because CSNK2B directly phosphorylates HDAC6 and increases cytoplasmic deacetylase activity
  • interaction partner of the adiponectin receptor 1 (ADIPOR1) N-terminus (interaction of ADIPOR1 with the tetrameric complex and CSNK2B is as a key player in adiponectin signaling)
