Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). AP-4 complex subunit sigma-1 is a protein that in humans is encoded by the AP4S1 gene.[1]

Function

The heterotetrameric adaptor protein (AP) complexes sort integral membrane proteins at various stages of the endocytic and secretory pathways. AP4 is composed of 2 large chains, beta-4 (AP4B1) and epsilon-4 (AP4E1), a medium chain, mu-4 (AP4M1), and a small chain, sigma-4 (AP4S1, this gene).[1]

Clinical relevance

It is currently hypothesized that AP4-complex-mediated trafficking plays a crucial role in brain development and functioning.[2]
