HY5 (DF0000633)

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.

hY5 Y scRNA gene / pseudogene


Human hY5 scRNA gene and related pseudogenes. While this ncRNA was originally identified as "4.5S RNA", GB accession K01106 [1], the human Y5 scRNA source is GB accession NR_001571.2.
