Store at -20°C, for extended storage, conserve at -20°C or -80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
This gene is located in the surfeit gene cluster, a group of very tightly linked genes that do not share sequence similarity. The gene demonstrates features of a housekeeping gene, being ubiquitously expressed, and the encoded protein has been localized to the nucleolus. The protein includes motifs found in both the mouse and fish orthologs, which suggests a putative function as a nucleolar-matrix protein with nucleic acid-binding properties, based on characteristics determined in mouse.
Binds to both DNA and RNA in vitro, with a stronger binding capacity for RNA. May represent a nucleolar constitutive protein involved in ribosomal biosynthesis or assembly.
Expressed in all tissues tested, including heart, brain, spleen, lung, liver, muscle, kidney and testis.
