I am doing transcript annotation of which i found one transcript was represented as chloroplast envelope membrane -like (LOC104000161) transcript variant misc_RNA. I am not aware what it represents.
any transcript or RNA product that cannot be defined by other RNA keys (prim_transcript, precursor_RNA, mRNA, 5'UTR, 3'UTR, exon, CDS, sig_peptide, transit_peptide, mat_peptide, intron, polyA_site, ncRNA, rRNA and tRNA)
misc_RNA is short for miscellaneous RNA, a general term for a series of miscellaneous small RNA. It serves a variety of functions, including some enzyme-like catalysis and processing RNA after it is formed. Besides, some of these small RNAs may serve as switches. Others, called RNAi, silence genes by tagging their mRNA for destruction. Maybe some of these small RNAs serve as gene switches, turning genes on and off, or just silence genes.
