Target Information
SIK3 (QSK) is a serine/threonine-protein kinase belonging to the QIK subfamily.
Phosphorylation of SIK3 by LKB1 through 14-3-3 binding enhances its catalytic activity and leads to localization in punctate cytoplasmic structures.
Overexpression of SIK3 promotes G1/S cell cycle progression in ovarian cancer.
Mutations (H331L and A1103V) have been observed at significant frequency in breast cancer.
SIK3 acts as a novel tumor-associated antigen (TAA) and a positive regulator of mTOR signaling by triggering degradation of DEPTOR, an mTOR inhibitor.
It is involved in dynamic regulation of mTOR signaling during chondrocyte differentiation and negatively regulates the cAMP signaling pathway, possibly through CRTC2/TORC2 and CRTC3/TORC3.
