Cloning of AIP1, a novel protein that associates with the apoptosis-linked gene ALG-2 in a Ca2+-dependent reaction.
ALG-2 is a 22-kDa calcium-binding protein necessary for cell death induced by different stimuli in 3DO T-cell hybridoma. 3DO cell clones depleted of ALG-2 protein exhibit normal caspases activation, suggesting that ALG-2 function is required downstream or is independent of caspase proteases activity for apoptosis to occur. Using the yeast two-hybrid screening system, we have isolated and charac...
متن کاملALG-2, a multifunctional calcium binding protein?
ALG-2 was originally discovered as a pro-apoptotic protein in a genetic screen. Due to its ability to bind calcium with high affinity it was postulated to provide a link between the known effect of calcium in programmed cell death and the molecular death execution machinery. This review article discusses the current knowledge on the structure and potential function of this protein. Several puta...
متن کاملTwo forms of the apoptosis-linked protein ALG-2 with different Ca(2+) affinities and target recognition.
The apoptosis-linked gene ALG-2 encodes a Ca(2+)-binding protein of the penta EF-hand family. To investigate the Ca(2+) binding properties of the recombinant ALG-2 protein, we have cloned ALG-2 cDNA from mouse liver mRNA. Sequence analysis showed that two types of clones were present. One (named ALG-2,5) corresponds to the published ALG-2 sequence (Vito, P., Lacana, E., and D'Adamio, L. (1996) ...
متن کاملALG-2 interacting protein-X (Alix) is essential for clathrin-independent endocytosis and signaling
The molecular mechanisms and the biological functions of clathrin independent endocytosis (CIE) remain largely elusive. Alix (ALG-2 interacting protein X), has been assigned roles in membrane deformation and fission both in endosomes and at the plasma membrane. Using Alix ko cells, we show for the first time that Alix regulates fluid phase endocytosis and internalization of cargoes entering cel...
متن کاملNuclear translocation of the calcium-binding protein ALG-2 induced by the RNA-binding protein RBM22.
By yeast two-hybrid screening using the calcium-binding protein ALG-2 as bait a new target of ALG-2 was identified, the RNA-binding protein RBM22. In order to confirm these interactions in vivo we prepared fluorescent constructs by using the monomeric red fluorescent protein to label ALG-2 and the enhanced green fluorescent protein to label RBM22. Confocal microscopy of NIH 3T3 cells transfecte...
