Event=Alternative splicing; Named isoforms=7; Comment=Many isoforms may exist depending on the occurrence and length of inserts at the x, y or z splice site. Four 'z' isoforms can be produced with inserts of 0, 8, 11 or 19 AA. Isoform 3 and isoform 6 lack any 'z' insert.

Domain (CC)
The NtA domain, absent in TM-agrin, is required for binding laminin and connecting to basal lamina.; DOMAIN: Both laminin G-like 2 (G2) and laminin G-like 3 (G3) domains are required for alpha-dystroglycan/DAG1 binding. G3 domain is required for C-terminal heparin, heparan sulfate and sialic acid binding (By similarity).
