UniProtKB - P85171 (MDGA1_RAT)
Protein
MAM domain-containing glycosylphosphatidylinositol anchor protein 1
Gene
Mdga1
Organism
Rattus norvegicus (Rat)
Status
Functioni
Required for radial migration of cortical neurons in the superficial layer of the neocortex (By similarity). Plays a role in the formation or maintenance of inhibitory synapses. May function by inhibiting the activity of NLGN2.By similarity2 Publications

Expressioni
Tissue specificityi
High levels detected in developing central and peripheral nervous systems with little expression elsewhere. In brain, highest levels in cerebral cortex and hindbrain at E15. At postnatal day 1, highest levels in basilar pons and superficial layers of the neocortex. In the developing spinal cord, restricted to a subpopulation of neurons in the dorsal and spinal ventral cord, probably D1 interneurons. Expressed in brain.2 Publications

Interactioni
Subunit structurei
Interacts heterophilically through its MAM domain with proteins in axon-rich regions and through its Ig-like domains with proteins in differentiating muscle (By similarity).
Interacts (through the Ig-like domains) with NLGN2.
