Testicular protein kinase 1 (TESK1) is a serine/threonine kinase with a structure composed of a kinase domain related to those of LIM-kinases and a unique C-terminal proline-rich domain. Like LIM-kinases, TESK1 phosphorylated cofilin specifically at Ser-3, both in vitro and in vivo. When expressed in HeLa cells, TESK1 stimulated the formation of actin(More)
LIM-kinase 1 (LIMK1) is a serine/threonine kinase that phosphorylates cofilin and regulates actin-filament dynamics. LIMK1, which contains two LIM domains and a single PDZ domain, localizes predominantly in the cytoplasm, but its mutant, deleted with the PDZ domain, localizes mainly in the nucleus, thereby indicating that the PDZ domain plays a role in the(More)
LIM-kinase 1 (LIMK1, where LIM is an acronym of the three gene products Lin-11, Isl-1 and Mec-3) is a serine/threonine kinase that phosphorylates cofilin and regulates actin cytoskeletal reorganization. LIMK1 contains two LIM domains and a PDZ (an acronym of the three proteins PSD-95, Dlg and ZO-1) domain in the N-terminal half and a kinase domain in the(More)
LIM-containing protein kinase 1 (LIMK1) is a serine/threonine kinase with a structure composed of two LIM domains, a PDZ domain, and a protein kinase domain. We examined the subcellular localization of LIMK1 and its variously deleted mutants in HeLa cells by transfection with these cDNAs. Immunofluorescence analysis revealed that the full-length LIMK1 and(More)
Multidrug resistance (MDR) transporters are capable of secreting structurally and functionally unrelated toxic compounds from the cell. Among this group are ATP-binding cassette (ABC) transporters. These membrane proteins are typically arranged as either hetero- or homo-dimers of ABC half-transporters with each subunit consisting of a membrane domain fused(More)
The majority of Crenarchaeota utilize the cell division system (Cdv) to divide. This system consists of three highly conserved genes, cdvA, cdvB and cdvC that are organized in an operon. CdvC is homologous to the AAA-type ATPase Vps4, involved in multivesicular body biogenesis in eukaryotes. CdvA is a unique archaeal protein that interacts with the(More)
