Article Title: A Chaperone Complex Formed by HSP47, FKBP65 and BiP Modulates Telopeptide Lysyl Hydroxylation of Type I Procollagen

doi: 10.1002/jbmr.3095

Figure Lengend Snippet: LH2, FKBP65, HSP47 and BiP interact. A-C. Protein levels of LH2 were altered in cells with mutations in FKBP10 and SERPINH1. BiP levels were decreased in HSP47 defective cells. D-E. Rescue experiment using FKBP10-/- cells transfected with FKBP10 tagged vector. LH2 levels were rescued by expression of wildtype FKBP65 protein. F. Co-immunoprecipitation of endogenous LH2, FKBP65, HSP47 and BiP in human osteoblasts (OB) with specific antibodies. LH2 immunoprecipitated HSP47 and BiP. G. Co-immunoprecipitation of tagged FKBP65 and LH2 in OB cells. LH2 and FKBP65 immunoprecipitated each other, including both LH2 isoforms, respectively.

Figure Lengend Snippet: Functional analyses of FH -regulated Cys residues. (a) Percentage of FH -regulated Cys residues predicted to be functional using the informatics tool Mutation Assessor (R ≥1.5, n ≥2). (b) Gene ontology analysis of FH -regulated Cys residues. (c) Correlation between genes containing FH -regulated Cys residues and genetic alterations in kidney cancer (RCC). Statistical significance was assessed using Student’s t -test (two-tailed, unpaired); ** P < 0.01. (d) SMARCC1 C520 lies in the SWIRM domain and is highly conserved. (e) SMARCC1 C520 lies at the SNF5 subunit interface. (f) SMARCC1 C520 undergoes FH -regulated changes in occupancy in HLRCC cells ( n = 3 independent experiments). (g) SMARCC1 C520E mutation limits co-immunoprecipitation with SNF5 in HEK-293 cells co-overexpressing FLAG-tagged SNF5 with Myc-tagged SMARCC1. (h) SMARCC1 S-succination can be detected in FH-deficient and FH WT HLRCC cell lines after IP of endogenous SMARCC1. (i) SNF5 demonstrates decreased co-immunoprecipitation and decreased levels in FH−/− HLRCC cells. Left: Results from SWI/SNF complex co-immunoprecipitation with BRG1 antibody. Right: Endogenous levels of SWI/SNF complex members in HLRCC cells. Representative images from two independent experiments are shown in g-i. Uncropped scans of immunoblots are provided in . (j) EZH2 inhibitors exhibit modest selectivity for FH-deficient HLRCC cells. UOK262 FH −/− or FH WT spheroids were treated with GSK126 (21 days; 1, 2, 4, 8, 16 μM) and % viability plotted relative to the vehicle treated spheroids. Data is presented as mean ± s.d.; n = 3/group. (k) EZH2 inhibitors are toxic to HLRCC spheroids. UOK262 FH −/− spheroids were treated with vehicle or EPZ6438 (14 days; 5 μM). Figure is representative of 6 replicates.
