AP4B1
An Error has occurred retrieving Wikidata item for infobox AP-4 complex subunit beta-1 is a protein that in humans is encoded by the AP4B1 gene.[1][2]
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, this protein) and epsilon-4 (AP4E1), a medium chain, mu-4 (AP4M1), and a small chain, sigma-4 (AP4S1)[2]
Interactions
AP4B1 has been shown to interact with AP4M1.[3]
Clinical relevance
AP4-complex-mediated trafficking plays a crucial role in brain development and functioning.[4][5]
