Visinin-like protein 1 (VSNL1), also known as VILIP1, is a calcium
sensor protein expressed exclusively in neurons. Highest levels of VSNL1 expression are found
in cerebellar Purkinje cells. VSNL1 has been implicated in the modulation of cell signaling
cascades via regulation of adenyl cyclase activity (Braunewell et al., 1997). Additionally, VSNL1
has been associated with amyloid plaques and neurofibrillar tangles in Alzheimer
