Guanine deaminase - GDA - Homo sapiens | |||||||
| LIG_PDZ_Class_1 | 449 | 454 | Binary | Pre‑translational | Alternative splicing removes the PDZ-binding motif of Guanine deaminase (GDA) (Nedasin), abrogating binding to Disks large homolog 3 (DLG3). Isoform 1 of Guanine deaminase (GDA) (Nedasin S) is predominately expressed in neuronal tissues and binds PDZ domains. Isoform 3 of Guanine deaminase (GDA) (Nedasin V1), which is predominately expressed in non-neuronal tissues, does not bind PDZ domains. The presence of Nedasin S inhibits binding of NMDA receptors and K+ channels to PDZ domain-containing proteins such as members of the MAGUK family. This suggests that GDA might modulate the receptor clustering function of the PDZ domains of MAGUK family members, and this modulation is regulated by alternative splicing of GDA transcripts. | ||
