AP4M1 gene

adaptor related protein complex 4 mu 1 subunit

From NCBI Gene:

This gene encodes a subunit of the heterotetrameric AP-4 complex. The encoded protein belongs to the adaptor complexes medium subunits family. This AP-4 complex is involved in the recognition and sorting of cargo proteins with tyrosine-based motifs from the trans-golgi network to the endosomal-lysosomal system.

From UniProt:

Component of the AP-4 complex, a novel type of clathrin- or non-clathrin-associated protein coat involved in targeting proteins from the trans-Golgi network (TGN) to the endosomal-lysosomal system. Plays a role in the intracellular trafficking of APP from the trans-Golgi network (TGN) to endosomes, and thereby inhibits amyloidogenic processing of APP.

  • Spastic paraplegia 50, autosomal recessive

From UniProt:

Cerebral palsy, spastic quadriplegic 3 (CPSQ3): A non-progressive disorder of movement and/or posture resulting from defects in the developing central nervous system. Affected individuals present postnatally with early infantile hypotonia, delayed psychomotor development, strabismus, lack of independent walking and severe mental retardation. They develop progressive spasticity of all limbs with generalized hypertonia, hyperreflexia, and extensor plantar responses by the end of the first year of life. Speech is absent or limited. Pseudobulbar signs, such as drooling, stereotypic laughter, and exaggerated jaw jerk, are part of the clinical picture. [MIM:612936]
