Agrn^Gt(Ex192)Byg

Insertion of a gene trap construct, pGT1.8TM, into the gene between the two exons encoding the N-terminal seqences of the agrin isoforms. The insertion abolished activity of the long N-terminal basal laminae isoform (LN-agrin) but had no detectable affects on the short N-terminal cell associated isoform (SN-agrin). (J:64996)
