The Zyxin/Ajuba family of cytosolic LIM domain-containing proteins has the potential to shuttle from sites of cell adhesion into the nucleus and thus can be candidate transducers of environmental signals. To understand Ajuba's role in signal transduction pathways, we performed a yeast two-hybrid screen with the LIM domain region of Ajuba. We identified the atypical protein kinase C (aPKC) scaff...
Lysine-specific demethylase 1 (LSD1) - also known as KDM1A - is the first identified histone demethylase. LSD1 is highly expressed in numerous human malignancies and has recently emerged as a target for anticancer drugs. Owing to the presence of several functional domains, we speculated that LSD1 could have additional functions other than histone demethylation. P62 - also termed sequestasome 1 ...
We reported that kelch-like protein 3 (KLHL3)-Cullin3 E3 ligase ubiquitinates with-no-lysine kinase 4 (WNK4) and that impaired WNK4 ubiquitination causes pseudohypoaldosteronism type II, a hereditary hypertensive disease. However, we also found that KLHL3-induced WNK4 degradation could not be inhibited completely by a proteasome inhibitor. Rather, on exposure, for 24 h, of HEK293T cells express...

Functional analyses of PDB (Paget's disease of bone)-associated mutants of the p62 [also known as SQSTM1 (sequestosome 1)] signalling adaptor protein represent an interesting paradigm for understanding not only the disease mechanism in this skeletal disorder, but also the critical determinants of ubiquitin recognition by an ubiquitin-binding protein. The 11 separate PDB mutations identified to ...
Proteolytic systems and the aggresome pathway contribute to preventing accumulation of cytotoxic aggregation-prone proteins. Although polyubiquitylation is usually required for degradation or aggresome formation, several substrates are processed independently of ubiquitin through a poorly understood mechanism. Here, we found that p62/SQSTM1, a multifunctional adaptor protein, was involved in th...
Cystic fibrosis is the most common inherited lethal disease in Caucasians. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), of which the cftr ΔF508 mutation is the most common. ΔF508 macrophages are intrinsically defective in autophagy because of the sequestration of essential autophagy molecules within unprocessed CFTR aggregates. Defective autophagy...
FAT10 is a ubiquitin-like modifier proposed to function in apoptosis induction, cell cycle control and NF-κB activation. Upon induction by pro-inflammatory cytokines, hundreds of endogenous substrates become covalently conjugated to FAT10 leading to their proteasomal degradation. Nevertheless, only three substrates have been identified so far to which FAT10 becomes covalently attached through a...
The Semliki Forest virus (SFV) spike is composed of three copies of a membrane protein heterodimer. The two subunits of this heterodimer (p62 and E1) are synthesized sequentially from a common mRNA together with the capsid (C) in the order C-p62-E1. In this work heterodimerization of the spike proteins has been studied in BHK 21 cells. The results indicate that: (a) the polyprotein is cotransla...
p62, as a scaffolding/adaptor protein, is involved in multiple physiological processes include inflammation, autophagy and mitosis. However, the influence of p62 in cancer patients has not been comprehensively investigated. Moreover, the prognostic value of p62 for the survival of patients with solid tumors remains controversial. In this present meta-analysis, twenty suitable articles were iden...
