General annotation (Comments)

Function

Required for learning most likely through its role in synaptic plasticity following NMDA receptor signaling.

Subunit structure

Interacts through its PDZ domains with GRIN2B and SYNGAP1. Interacts through its guanylate kinase-like domain with DLGAP1, DLGAP2, DLGAP3 and DLGAP4 By similarity. Interacts through its PDZ domains with APC. Interacts through its first two PDZ domains with ERBB4. Interacts through its third PDZ domain with NLGN1, and probably with NLGN2 and NLGN3. Interacts with FRMPD4 (via C-terminus). Ref.1 Ref.6 Ref.7 Ref.10

Involvement in disease

Defects in DLG3 are the cause of mental retardation X-linked type 90 (MRX90) [MIM:300189]. Mental retardation is characterized by significantly sub-average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. Non-syndromic mental retardation patients do not manifest other clinical signs. Ref.8

Sequence similarities

Belongs to the MAGUK family.

Contains 1 guanylate kinase-like domain.

Contains 3 PDZ (DHR) domains.

Contains 1 SH3 domain.

Ontologies

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Note: Named isoforms=2.
Isoform 1 (identifier: Q92796-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q92796-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-336: Missing.
     337-381: HISHNSSLGY...RHMLAEEDFT → MERARKFSGS...LRSLRPGGDA
     592-606: DFPGLSDDYYGAKNL → SIKTKRKKSFRLSRKFPFYKSKENMAQESSIQEQGVTSNTSDSESSS
