Microproteins are peptides composed of 100 amino acids (AA) or less, encoded by small open reading frames (smORFs). It has been demonstrated that microproteins participate in and regulate a wide range of functions in cells. However, the annotation and identification of microproteins is challenging in part owing to their low molecular weight, low abundancy, and hydrophobicity. These factors have led to the un-annotation of smORFs in genome processing and have made their identification at the protein level difficult. Large-scale enrichment of microproteins in proteogenomics has made it possible to efficiently identify microproteins and discover unannotated smORFs in Saccharomyces cerevisiae. Here, we integrated four microprotein-specific enrichment strategies to enhance coverage. We identified 117 microproteins, verified 31 missing proteins (MPs), and discovered 3 novel smORFs. In total, 31 proteins were confirmed as MPs by spectrum quality checking. Three novel smORFs (YKL104W-A, YHR052C-B, and YHR054C-B) were reserved after spectrum quality checking, peptide synthesizing, homologue matching, etc. This study not only demonstrates that there are potential smORF candidates to be annotated in an extensively studied organism, but also presents an efficient strategy for the discovery of small MPs. All MS datasets have been deposited to the ProteomeXchange with identifier PXD008586 (Username: firstname.lastname@example.org; Password: UNEbNk3j).

Work consisting of the designation of an article or book as retracted in whole or in part by an author or authors or an authorized representative. It identifies a citation previously published and now retracted through a formal issuance from the author, publisher, or other authorized agent, and is distinguished from RETRACTION OF PUBLICATION, which identifies the citation retracting the original published item.
Adaptive antiviral defense mechanisms, in archaea and bacteria, based on DNA repeat arrays called CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS (CRISPR elements) that function in conjunction with CRISPR-ASSOCIATED PROTEINS (Cas proteins). Several types have been distinguished, including Type I, Type II, and Type III, based on signature motifs of CRISPR-ASSOCIATED PROTEINS.
A conserved AMINO ACID SEQUENCE located in the intracellular domains of a family of transmembrane proteins that negatively regulate the signal transduction processes emanating from transmembrane proteins containing IMMUNORECEPTOR TYROSINE-BASED ACTIVATION MOTIFS. The CONSENSUS SEQUENCE of this motif is I(or V)LXYXXL(or V) (where X denotes any amino acid). Also known as ITIM motifs.
SNARE proteins where the central amino acid residue of the SNARE motif is an ARGININE. They are classified separately from the Q-SNARE PROTEINS where the central amino acid residue of the SNARE motif is a GLUTAMINE. This subfamily contains the vesicle associated membrane proteins (VAMPs) based on similarity to the prototype for the R-SNAREs, VAMP2 (synaptobrevin 2).
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
