Involved in 2 distinct lysosomal degradation pathways: acts as a regulator of autophagy and as a regulator of G protein-coupled receptors turnover. Regulates degradation in lysosomes of a variety of G protein-coupled receptors via its interaction with GPRASP1/GASP1. . This is the function of BECN2 (beclin 2, Ensembl gene identifier ENSG00000196289).
