The
The process function class (pfclass) of an ncRNA is based on the cellular process in which it takes part in(e.g DNA duplication, RNA replication, protein translation etc). In addition, a second term and third term specifying a sub-process or the specific function of the ncRNA, may be added to the term describing the main process. For example, the snRNA U1 will be assigned to the pfclass RNA_processing_splicing, and Rnase P RNAs to the pfclass RNA_processing_cleavage. Each ncRNA is assigned to one or more of 26 pfclasses. Here we itemize all pfclass:
