Brain-specific angiogenesis inhibitor 1-associated protein 2 - BAIAP2 -  Homo sapiens
LIG_PDZ_Class_1516521BinaryPre‑translationalAlternative splicing removes the PDZ-binding motif of Isoform BAIAP2-alpha of Brain-specific angiogenesis inhibitor 1-associated protein 2 (BAIAP2), abrogating binding to Disks large homolog 3 (DLG3). The SH3 domain of Isoform BAIAP2-alpha of Brain-specific angiogenesis inhibitor 1-associated protein 2 (BAIAP2) also binds to SH3 and multiple ankyrin repeat domains protein 1 (SHANK1), meaning it can link two prominent proteins of the postsynaptic NMDA-receptor complex, namely SHANK1 and DLG3.

Guanine deaminase - GDA -  Homo sapiens
LIG_PDZ_Class_1449454BinaryPre‑translationalAlternative 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.

Plasma membrane calcium-transporting ATPase 4 - ATP2B4 -  Homo sapiens
LIG_PDZ_Class_112361241BinaryPre‑translationalAlternative splicing removes the PDZ-binding motif of Plasma membrane calcium-transporting ATPase 4 (ATP2B4), abrogating binding to Disks large homolog 3 (DLG3). Disks large homolog 3 (DLG3) did not bind to 'b' isoform of PMCA2. There is therefore an interaction selectivity between 'b' isoforms of ATP2B4 and DLG3 as opposed to the promiscuity of 'b' isoforms of ATP2B2 and ATP2B4 in interacting with other SAPs. Same study DLG4, DLG2 and DLG1 shown to bind to PDZ-binding motifs in 'b' isoforms of ATP2B4 and ATP2B2.
