Background: Fc mu R/FAIM3

The human FAIM3 gene (also known as FCMR or TOSO), is a transmembrane sialoglycoprotein expressed mainly by lymphocytes. FAIM3 is a type I membrane protein with an intracellular C-terminal domain and an extracellular N-terminal domain (1). The extracellular domain has homology to the immunoglobulin variable region domains (1) and FAIM3 is identified as an Fc receptor for IgM (2, 3). The amino acid sequence of human FAIM3 is 58% and 55% identical to that of mouse and rat FAIM3, respectively. FAIM3 was shown to be over-expressed in chronic lymphocytic leukemia (CLL) (4) and associated with disease progression (5, 6). FAIM3 has also been linked to the homeostasis and activation of the innate immune system (7). Interestingly, there is growing evidence that neurodegenerative diseases are associated with the activation of the immune surveillance system. This system is responsible for controlling danger signals and responding accordingly to the magnitude and duration of the threat (8, 9).
