Related Product Information for GLK active protein

GLK is a member of the STE20 family of serine/threonine protein kinases and contains N-terminal catalytic domain and C-terminal regulatory domain. GLK is upstream of the MEKK1 target and is stimulated by UV radiation and TNF-? and can lead to the activation of the JNK signaling pathway. GLK can directly activate PKC-? during TCR signaling and people with systemic lupus erythematosus show considerable enhanced GLK expression and activation of PKC-? and the kinase IKK in T cells. GLK can act as a pro-apoptotic kinase which orchestrates activation of BAX via the concerted posttranscriptional modulation of PUMA, BAD, and BIM.

NCBI Description

This gene encodes a member of the mitogen-activated protein kinase kinase kinase kinase family. The encoded protein activates key effectors in cell signalling, among them c-Jun. Alternatively spliced transcripts encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

Uniprot Description

KHS2: an ubiquitous protein kinase of the STE20 family. May play a role in the response to environmental stress. Regulated by amino acids and acts upstream of mTORC1 and JNK. Required for maximal S6K and 4E-BP1 phosphorylation. Interacts with PPP2R5E, a regulatory subunit of PP2A. Following amino acid withdrawal, pS170 is dephosphorylated via PP2A. The dephosphorylation of pS170 by PP2A in response to amino acid restriction inhibits mTORC1 signaling. The inhibition of PPP2R5E expression prevents the dephosphorylation of KHS2 pS170, impairing mTORC1 inhibition during amino acid withdrawal. Three alternatively spliced isoforms have been described.
