Biological function summary
KLHL22 is involved in regulating protein turnover by targeting proteins for ubiquitination influencing processes such as cell cycle progression and signal transduction. It operates as an adaptor protein within the Cullin-RING E3 ubiquitin ligase complex linking substrate proteins to the complex for ubiquitination. By regulating the degradation of key proteins KLHL22 impacts cellular homeostasis and various physiological responses demonstrating its importance in maintaining cellular order.
Pathways
KLHL22 contributes to the ubiquitin-proteasome pathway where it assists in protein degradation and turnover maintaining protein quality control. It also associates with the cell cycle regulation pathway interacting with proteins such as CUL3 within the Cullin-RING complex to ensure cell cycle progression by timely degradation of cyclins and other regulatory proteins. These pathway involvements highlight KLHL22's role in cellular regulation and proteostasis.

기능
Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complex required for chromosome alignment and localization of PLK1 at kinetochores. The BCR(KLHL22) ubiquitin ligase complex mediates monoubiquitination of PLK1, leading to PLK1 dissociation from phosphoreceptor proteins and subsequent removal from kinetochores, allowing silencing of the spindle assembly checkpoint (SAC) and chromosome segregation. Monoubiquitination of PLK1 does not lead to PLK1 degradation (PubMed : 19995937, PubMed : 23455478). The BCR(KLHL22) ubiquitin ligase complex is also responsible for the amino acid-stimulated 'Lys-48' polyubiquitination and proteasomal degradation of DEPDC5. Through the degradation of DEPDC5, releases the GATOR1 complex-mediated inhibition of the TORC1 pathway. It is therefore an amino acid-dependent activator within the amino acid-sensing branch of the TORC1 pathway, indirectly regulating different cellular processes including cell growth and autophagy (PubMed : 29769719).
