Predicted to enable identical protein binding activity. Predicted to be involved in several processes, including endoplasmic reticulum tubular network organization; negative regulation of cysteine-type endopeptidase activity involved in apoptotic process; and positive regulation of L-glutamate import across plasma membrane. Predicted to be located in cytosol and endoplasmic reticulum membrane. Predicted to be integral component of endoplasmic reticulum membrane. Predicted to be part of Sec61 translocon complex. Predicted to be integral component of membrane. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 61. Orthologous to human ARL6IP1 (ADP ribosylation factor like GTPase 6 interacting protein 1). [provided by Alliance of Genome Resources, Apr 2022]
