Pacer (also known as Rubicon-like) is a protein that in humans is encoded by the RUBCNL gene.[5] Pacer has been shown to increase cellular autophagy through regulation of PI3KC3.[6]

Pacer contains a Rubicon homology (RH) domain at its C-terminus, which mediates binding to small GTPase Rab7.[7][8] This domain is shared with RH domain containing family members Rubicon and PLEKHM1.[9] Whereas Pacer appears to upregulate autophagic activity, Rubicon is a negative regulator of autophagy.[9]
