Physical and Functional Interaction between hMSH5 and c-Abl

Physical and functional interaction between hMSH5 and c-Abl.

Despite being a member of the mismatch repair family of proteins, the biological functions of hMSH5 in human cells are presently elusive. Here, we report a novel physical and functional interaction between hMSH5 and c-Abl; the latter is a critical non-receptor tyrosine kinase involved in many critical cellular functions including DNA damage response, in which the kinase activity is normally sup...

Functional interaction between c-Abl and the p21-activated protein kinase gamma-PAK.

A member of the p21-activated protein kinase (PAK) family, gamma-PAK has cytostatic properties and is activated by cellular stresses such as hyperosmolarity or DNA damage. We report herein that gamma-PAK is associated in vivo with the nonreceptor protein tyrosine kinase c-Abl. gamma-PAK phosphorylates c-Abl on sites located in the kinase domain, in a region that is implicated in protein-protein...

Physical and functional interaction between WRNIP1 and RAD18.

WRN interacting protein 1 (WRNIP1) was originally identified as a protein that interacts with the Werner syndrome responsible gene product (WRN). WRNIP1 is a highly conserved protein from E. coli to humans. Genetic studies in budding yeast suggested that the yeast orthlog of WRNIP1, Mgs1, may function in a DNA damage tolerance pathway that is similar to, but distinct from, the template-switch d...

Physical and functional interaction between integrins and hERG potassium channels.

Integrins are adhesion receptors capable of transmitting intracellular signals that regulate many different cellular functions. Among integrin-mediated signals, the activation of ion channels can be included. We demonstrated that a long-lasting activation of hERG (human ether-a-go-go-related gene) potassium channels occurs in both human neuroblastoma and leukaemia cells after the activation of ...
