Cloning and characterization of a novel splice variant of the brain-specific protein densin-180
Densin-180 is a brain-specific synaptic protein of the o-sialoglycoprotein family. It functions in specific adhesion between presynaptic and postsynaptic membranes at glutamatergic synapses. We have cloned a novel splice variant of densin-180 from a fetal brain cDNA library and termed it LRRC7. It is located on 1p31 and consists of 8 exons. It encodes a putative protein of 216 amino acids which contains a nuclear localization signal and four leucine-rich repeats (LRRs). LRRs are 20-29 residue sequence motifs present in a number of proteins with diverse functions. Expression analysis of LRRC7 shows it is expressed ubiquitously while its splice variant densin-180 is brain-specific.
