Function

[1433Z_HUMAN] Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.^[1] ^[2] ^[3] ^[4] ^[5] [UBP8_HUMAN] Hydrolase that can remove conjugated ubiquitin from proteins and therefore plays an important regulatory role at the level of protein turnover by preventing degradation. Converts both 'Lys-48' an 'Lys-63'-linked ubiquitin chains. Catalytic activity is enhanced in the M phase. Involved in cell proliferation. Required to enter into S phase in response to serum stimulation. May regulate T-cell anergy mediated by RNF128 via the formation of a complex containing RNF128 and OTUB1. Probably regulates the stability of STAM2 and RASGRF1. Regulates endosomal ubiquitin dynamics, cargo sorting, membrane traffic at early endosomes, and maintenance of ESCRT-0 stability. The level of protein ubiquitination on endosomes is essential for maintaining the morphology of the organelle. Deubiquitinates EPS15 and controles tyrosine kinase stability. Removes conjugated ubiquitin from EGFR thus regulating EGFR degradation and downstream MAPK signaling. Involved in acrosome biogenesis through interaction with the spermatid ESCRT-0 complex and microtubules. Deubiquitinates BIRC6/bruce and KIF23/MKLP1.^[6] ^[7] ^[8] ^[9]

Publication Abstract from PubMed

The ubiquitin-specific protease 8 (USP8)/14-3-3 protein-protein interaction has recently been shown to exert a significant role in the pathogenesis of Cushing's disease (CD). USP8 is a deubiquitinase that prevents epidermal growth factor receptor (EGFR) degradation. Impairment of 14-3-3 binding leads to a higher deubiquitination of EGFR and results in a higher EGFR signaling and an increased production of adrenocorticotropic hormone. Here we report the high-resolution crystal structure of the 14-3-3 binding motif of USP8 surrounding Ser718 in complex with 14-3-3zeta and characterize the interaction with fluorescence polarization and isothermal titration calorimetry. Furthermore, we analyze the effect of USP8 mutations identified in CD on binding to 14-3-3.
