Abstract
Human restrictin proteins and nucleic acid sequences encoding them are provided. Antibodies which recognize human restrictin in human brain are disclosed. In the human brain, restrictin occurs as two major polypeptides of 180 and 160 kD located in fiber tracts. These polypeptides are similar to those seen in rat brain. Surprisingly, restrictin has also been found in the peripheral nerves of rats and humans The antibodies also detect a 170 kD polypeptide in MATRIGEL, an extracellular matrix product of rat EHS sarcoma cells widely used as a tissue culture substrate. Monoclonal antibodies to human restrictin and assays using the human restrictin protein, antibodies and DNA sequences are also provided.
Claims3
A method for detecting human restrictin in a sample comprising combining the sample with an antibody which binds to the protein fragment encoded by the 206/207N fragment of human restrictin, said 206/207N fragment consisting of nucleotides 2686-3165 of SEQ ID NO:
- 3, and detecting binding of the antibody to the human restrictin, thereby detecting the human restrictin in the sample.
