Peptidomic discovery of short open reading frame-encoded peptides in human cells.
-
ASNSD1-SEP detected by peptidomics in K562 cells, quantified by isotope dilution, and localized to the cytoplasm as a FLAG-tagged construct in HEK293T cells.
"examined the cellular concentrations (K562 cells) of three selected SEPs (ASNSD1-SEP, PHF19-SEP and H2AFx-SEP) using isotope dilution mass spectrometry"
Upstream ORF-Encoded ASDURF Is a Novel Prefoldin-like Subunit of the PAQosome.
Translation of non-canonical open reading frames as a cancer cell survival mechanism in childhood medulloblastoma.
-
ASDURF (ASNSD1-uORF) is a dependency of MYC-driven medulloblastoma cells, interacts directly with the prefoldin-like complex, and co-varies with prefoldin-like subunits in DepMap/PRISM knockout profiles.
"A microprotein encoded by one of these ORFs, ASNSD1-uORF or ASDURF, was upregulated, associated with MYC-family oncogenes, and promoted medulloblastoma cell survival through engagement with the prefoldin-like chaperone complex."
Actions speak louder than ORFs: A non-canonical microprotein promotes medulloblastoma oncogenesis.
