Peroxisomes are tiny organelles that control important and diverse metabolic processes via their interplay with other organelles, including the endoplasmic reticulum (ER). In this issue, Costello et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201607055) and Hua et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201608128) identify a peroxisome-ER contact site in human cells held together by a tethering complex of VAPA/B (vesicle-associated membrane protein-associated proteins A/B) and ACBD5 (acyl Co-A binding protein 5).
