Expression, purification, crystallization and preliminary crystallographic analysis of the human intracellular chloride channel protein CLIC4.
The human chloride intracellular channel protein CLIC4 has been crystallized by the hanging-drop vapour-diffusion technique using trisodium citrate as the precipitant. The best crystals were obtained by the microseeding method. The crystals diffracted to 2.2 A resolution and were found to belong to space group P121, with unit-cell parameters a = 73.19, b =86.05, c = 73.38 A, beta = 112.99 degre...
متن کاملInducible NOS-induced chloride intracellular channel 4 (CLIC4) nuclear translocation regulates macrophage deactivation.
Nuclear translocation of cytosolic CLIC4 is an essential feature of its proapoptotic and prodifferentiation functions. Here we demonstrate that CLIC4 is induced concurrently with inducible nitric oxide synthase (iNOS) and S-nitrosylated in proinflammatory peritoneal macrophages. Chemical inhibition or genetic ablation of iNOS inhibits S-nitrosylation and nuclear translocation of CLIC4. In macro...
متن کاملRegulation of CFTR chloride channel trafficking by Nedd4-2: role of SGK1
Introduction: The cystic fibrosis transmembrane conductance regulator (CFTR) chloride (Cl−) channel is an essential component of epithelial Cl− transport systems in many organs. CFTR is mainly expressed in the lung and other tissues, such as testis, duodenum, trachea and kidney. The ubiquitin ligase neural precursor cells expressed developmentally down-regulated protein 4-2 (Nedd4-2...
متن کاملmtCLIC/CLIC4, an organellular chloride channel protein, is increased by DNA damage and participates in the apoptotic response to p53.
mtCLIC/CLIC4 (referred to here as mtCLIC) is a p53- and tumor necrosis factor alpha-regulated cytoplasmic and mitochondrial protein that belongs to the CLIC family of intracellular chloride channels. mtCLIC associates with the inner mitochondrial membrane. Dual regulation of mtCLIC by two stress response pathways suggested that this chloride channel protein might contribute to the cellular resp...
متن کاملAbsence of chloride intracellular channel 4 (CLIC4) predisposes to acute kidney injury but has minimal impact on recovery
BACKGROUND CLIC4, a member of the CLIC family of proteins, was recently demonstrated to translocate to the nucleus in differentiating keratinocytes where it potentiates TGFβ-driven gene regulation. Since TGFβ signaling is known to play important roles in the fibrotic response to acute kidney injury, and since CLIC4 is abundantly expressed in kidney, we hypothesized that CLIC4 may play a role in...
