Objective:
To isolate the long coding sequence of human novel gene C17orf62 which is named as C17orf62-L by us, and analyze its effects on cell viability, subcellular localization, and expression profile in multiple cell lines.
Methods:
RT-PCR (reverse transcription polymerase chain reaction ) was used to clone C17orf62-L which encoded 187 amino acids from human multi-tissue cDNA library. We used bioinformatics analysis to identify structural characteristics of C17orf62-L, and RT-PCR to detect its expression. By Laser Scanning Confocal Microscopy we identified its subcellular localization of C17orf62-L. Furthermore, flow cytometry experiment was used to validate whether overexpression of C17orf62-L could influence cell phenotypes and Western blot was used to study related mechanisms.
Results:
C17orf62-L was cloned and constructed into the pcDNA-and pEGFP-expression plasmids. C17orf62-L had signal peptide and transmembrane domain.C17orf62-L was widely expressed in multiple cell lines and was validated partial co-localization with Golgi apparatus. Functional studies showed C17orf62-L could induce cell death accompanied with rising of cleaved PARP(poly ADP-ribose polymerase).
Conclusion:
Human C17orf62 is a novel cell death inducing gene.
