Chromosome 11 open reading frame one, also known as C11orf1, is a protein-coding gene. It has been found by yeast two hybrid screen to bind to SETDB1 a histone protein methyltranferase enzyme. SETDB1 has been implicated in Huntington's disease, a neurodegenerative disorder.
C11orf1 is a nuclear protein with unknown function but has been shown to show preferential expression in some disease states in microarray data.
This protein is part of the UPF0686 superfamily. This family is characterized by the presence of a domain of unknown function (DUF)1143 shared by the family. This family DUF1143 has a domain that includes almost all,149, of the 150 amino acids in the human ortholog. C11orf1 has six spicesomal variants and one unspliced variant.
C11orf1 appears to be ubiquitously expressed at low levels but particularly high expression in the parathyroid. Expression data indicate expression in most tissues. This gene has also been found in one experiment to be under expressed in Huntington's disease patients while SETDB1 is over-expressed.
