Protein
Protein lifeguard 2
Gene
Faim2, Kiaa0950, Lfg, Lfg2, Nmp35
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

Antiapoptotic protein which protects cells uniquely from Fas-induced apoptosis. Regulates Fas-mediated apoptosis in neurons by interfering with caspase-8 activation. Plays a role in cerebellar development by affecting cerebellar size, internal granular layer (IGL) thickness, and Purkinje cell (PC) development.3 Publications

Pathology & Biotechi

Disruption phenotypei

Mice show reduced cerebellar size and internal granular layer (IGL) thickness in early developmental stages, delayed Purkinje Cell (PC) development, with an abnormal morphology and reduced cellular density, increased caspase-8 and caspase-3 activity in PCs and higher sensitivity to Fas-mediated apoptosis.1 Publication
