Antisense RNAs during early vertebrate development are divided in groups with distinct features.

ABSTRACT: Long noncoding RNAs or lncRNAs are a class of non-protein-coding RNAs that are >200 nt in length. Almost 50% of lncRNAs during zebrafish development are transcribed in an antisense direction to a protein-coding gene. However, the role of these natural antisense transcripts (NATs) during development remains enigmatic. To understand NATs in early vertebrate development, we took a computational biology approach and analyzed existing as well as novel data sets. Our analysis indicates that zebrafish NATs can be divided into two major classes based on their coexpression patterns with respect to the overlapping protein-coding genes. Group 1 NATs have characteristics similar to maternally deposited RNAs in that their levels decrease as development progresses. Group 1 NAT levels are negatively corr
