Abstract

Cutaneous leishmaniasis (CL) is caused by a kinetoplastid protozoan parasite Leishmania major, as a skin ulcer at the site of the sandfly bite. CL is curable and in most cases ulcers heal spontaneously within three to six months leaving a scar and disfiguration. Complete genome of L. major was reported in 2005 at the very initial phase of kinetoplastid parasite genome sequencing project. Presently, L. major genome is most studied and comprehensively annotated genome and therefore, it is being used as a reference genome for annotating recently sequenced Leishmanial genomes. A recent study reporting global transcriptome of L. major promastigotes, identified 1884 uniquely expressed non-coding RNAs (ncRNA) in L. major. In the current study, an in-depth analysis of the 1884 novel ncRNAs was carried out using a proteogenomic approach to identify their protein coding potential. Our analysis resulted in identification of eight novel protein coding genes based on mass spectrometry data. We have analyzed each of these eight novel CDS and in the process have improved the genome annotation of L. major on the basis of mass spectrometry derived peptide data. Although sequenced a decade ago, the improvement in the L. major genome annotation thus is an ongoing process.
