Heat Shock Generates Insoluble Ubiquitin-Positive Aggregates and Does Not Inactive Proteasomes, Related to Figure 1(A) UBQLN2 is not pelleted when cells are heat shocked post lysis. Cell lysates were incubated at 37 or 42C and then fractionated into soluble (S) and pellet (P) fraction. This indicates that UBQLN2 itself does not aggregate as a result of high temperature.(B) UBQLN2 levels are not upregulated in response to heat shock. HSP70 and GAPDH were used as a positive and negative controls, respectively.(C) Heat shock aggregates are insoluble in up to and including 1% SDS but are solubilized in 2% SDS. Blotting of soluble and pellet fractions with anti-ubiquitin and UQBLN2 antibodies confirmed dissolution of the aggregates in 2% SDS.(D) Proteasomes are active after heat shock. To confirm that proteasome activity was not affected by heat shock, we incubated U2OS and MEFs at the indicted temperatures for 2h. Cells were then harvested and cell lysates were incubated with the proteasome inhibitor MG132 or DMSO, followed by incubation with a fluorescent proteasome-activity probe, as indicated. The presence of fluorescently labeled beta-subunits at the same intensity under both heat stress and normal temperature, indicate that proteasome activity is not significantly affected by heat shock.(E) U2OS cells were treated with control or UBQLN2 siRNA and subjected to heat shock for the indicated times. Analysis of the pellet fraction revealed that insoluble ubiquitylated aggregates are generated within 5 min of heat shock, but that depletion of UBQLN2 does not noticeably alter the accumulation of these aggregates at any of the indicated time points.

Puromycin Does Not Upregulate UBQLN2 Levels and UBQLN2 Clears Nuclear Aggregated GFP-u, Related to Figure 2(A) Schematic representation on how the three fractions, total insoluble, nuclear soluble and total insoluble were generated.(B) Cells treated with puromycin were fractionated as indicated and treatment did not induce the nuclear localization of UBQLN2.(C) Puromycin treatment did not induce the upregulation of UBQLN2 protein.(D) Schematic showing the GFPu-NLS construct (Bennett et al., 2005).(E) HEK293 cells stably expressing GFPu-NLS were subject to heat shock for 2h at 42C and fractionated into soluble and insoluble fractions. GFPu-NLS recruited to the insoluble fraction after heat shock indicating its heat-induced aggregation.(F) GFPu-NLS cells were subject to heat shock for 2h at 42C and proteasome inhibition with 25 μM MG132 as indicated. UBQLN2 was immunoprecipitated and GFPu-NLS was found to co-immunoprecipitate only upon heat shock, consistent with UBQLN2 nuclear localization. Combined heat shock and proteasome inhibition increased the binding further.(G) GFPu-NLS cells were depleted of UBQLN2 or treated with a control non-targeting siRNA then treated with 50 μg/ml cycloheximide (CHX) for the indicated time to measure turnover. Turnover was quantified using data from three independent experiments.Error bars represent SE.

Background: Ubiquilin 2

Ubiquilin 2, also known as PLIC2 and Chap1, is a member of the ubiquilin protein family, which regulate the degradation of cellular proteins through proteasome or autophage-like pathways. Humans have four ubiquilin genes, each encoding a separate protein referred to as Ubiquilin 1, 2, 3 and 4. All ubiquilins contain an N-terminal ubiquitin-like (UBL) domain and a C-terminal ubiquitin-associated (UBA) domain, while the central part of the molecules are highly variable. The UBL domains bind subunits of the proteasome, and the UBA domains binds to polyubiquitin chains that are typically conjugated onto proteins marked for proteosomal degradation. Ubiquilin 2 has a unique region close to the C terminus containing 12 PXX tandem collagen like repeats, where P is proline and X is most cases valine, glycine, isoleucine or threonine. Teepu Siddique and his collaborators have identified mutations in the ubiquilin 2 gene leading to protein point mutations which were important contributors to several forms of amyotrophic lateral sclerosis (ALS) and Frontotemporal lobar degeneration (FTLD). Interestingly, these mutations involved alterations in proline residues in the PXX repeat region (P497H, P497S, P506T, P509S and P525S). Recently, the Lee and Trojanowski group investigated C9orf72 hexanucleotide expansion and ubiquilin 2 pathology in patients with ALS and FTLD by genetic analysis and immunohistochemistry and found distinct Ubiquilin 2 pathology in ALS and FTLD-TDP with C9orf72 expansion. C9orf72 hexonucleotide expansion is the most common cause to date of familial ALS and FTLD. Ubiquilin 2 protein is of different molecular size in mouse and human, 638 and 624 amino acids respectively. As a result the mouse protein, endogenously expressed in rodent 3T3 cells, runs on SDS-PAGE and western blots slightly slower than the human protein.
