U2 (DF0001076)

This model represents a noncoding RNA gene. Some ncRNA genes have transformed into, or become assimilated into transposons. Others occur in sufficient copy number that ab initio repeat finders may classify them as repetitive elements. This entry is used to correctly identify the gene and its pseudogenes and prevent misannotation.

U2 snRNA (spliceosomal RNA) gene / pseudogene


U2 snRNA genes are multicopy, and have spawned many hundreds of pseudogenes in human.
