Sorting nexin

Function

Sorting nexins (SNX) are proteins which enhance membrane association via their lipid-binding PX domain or via protein-protein association^[1]. The PX domain contains a phospholipid-binding motif.

SNX 1 regulates trafficking in the endosome compartment^[2].
SNX 3 regulates neurite formation^[3].
SNX 5 regulates retrograde trafficking of transmembrane cargo receptors^[4].

Relevance

SNX 2 is a potential marker of hyper functioning thyroid disorders^[5].
