Ribonuclease T2 is an

enzyme An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different mol ...

gene In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei ...

endoribonuclease In biochemistry, an endoribonuclease is a class of enzyme which is a type of ribonuclease (an RNA cleaver), itself a type of endonuclease (a nucleotide cleaver). It cleaves either single-stranded or double-stranded RNA, depending on the enzyme. Ex ...

. This ribonuclease gene is a novel member of the Rh/T2/S-glycoprotein class of extracellular ribonucleases. It is a single copy gene that maps to 6q27, a region associated with human malignancies and chromosomal rearrangement. RNASET2 has been reported as a tumour associated antigen in anaplastic large cell lymphoma and other lymphomas.
