The BCL-2 Family Reunion

The Proapoptotic Bcl-2 Family Member Bim

The bcl-2 family of proteins.

The bcl-2 family of proteins play an important role in the control of apoptosis. Family members exist which are either pro- or anti-apoptotic and their activity appears to control a checkpoint between signals from the cell surface and activation of the ICE-family of proteases. Despite having a key role to play in apoptosis, the mechanism of action of these proteins can only, at present, be infe...

Mtd, a novel Bcl-2 family member activates apoptosis in the absence of heterodimerization with Bcl-2 and Bcl-XL.

We have identified and characterized Mtd, a novel regulator of apoptosis. Sequence analysis revealed that Mtd is a member of the Bcl-2 family of proteins containing conserved BH1, BH2, BH3, and BH4 regions and a carboxyl-terminal hydrophobic domain. In adult tissues, Mtd mRNA was predominantly detected in the brain, liver, and lymphoid tissues, while in the embryo Mtd mRNA was detected in the l...

Ras and Rho GTPases A Family Reunion

Rap1, is required to define the position of the new bud. 1997). In vitro, this interaction is not sufficient to stimulate the GEF activity of Cdc24p, and one functional out-and Molecular Biology University College London come of this interaction in vivo, therefore, is likely to be the localization of Cdc24p to the presumptive bud site London WC1E 6BT United Kingdom (Zheng et al., 1995). In S. p...

[The role of bcl-2 family proteins in psoriasis].

Apoptosis is a physiological process of programmed cell death responsible for homeostasis in the body. In skin, apoptotic process regulates keratinocyte proliferation and differentiation in that way maintaining homeostasis of epidermal compartment. The process of apoptosis is controlled by proteins of the Bcl-2 family, several proapoptotic (Bax, Bak, Bad) and antiapoptotic (Bcl-2, Bcl-x(L)) pro...
