Summary
Sperm can translate messenger RNAs (mRNAs) into proteins, a process vital for fertility. Understanding this mRNA translation, RNA-binding proteins, and small noncoding RNAs offers new diagnostic and therapeutic approaches for male infertility.
Area of Science:
- Reproductive Biology
- Molecular Biology
- Genetics
Background:
- Male infertility affects 50% of cases, with 30% unexplained, necessitating deeper understanding of sperm function.
- Sperm were once thought translationally silent but evidence shows they synthesize proteins from messenger RNAs (mRNAs).
- mRNA translation in sperm during capacitation is poorly understood but crucial for fertility diagnostics.
Purpose of the Study:
- To review emerging research on sperm mRNA translation.
- To explore the roles of RNA-binding proteins (RBPs), small noncoding RNAs (sncRNAs), and epitranscriptomic marks in sperm function.
- To highlight the potential of sperm mRNA translation for improving fertility diagnosis and treatment.
Main Methods:
- Literature review of recent studies on sperm RNA biology and translation.
- Analysis of the components involved in mRNA translation within ejaculated sperm.
- Examination of the regulatory mechanisms involving RBPs, sncRNAs, and epitranscriptomic modifications.
Main Results:
- Sperm contain necessary factors for mRNA translation, including initiation and elongation factors, and ribosomal proteins.
- RBPs, sncRNAs, and epitranscriptomic marks regulate mRNA stability, localization, and translation in sperm.
- Altered sncRNA profiles are linked to male infertility, and RNA-protein interactions may underlie idiopathic infertility.
Conclusions:
- Sperm mRNA translation is a critical but understudied aspect of male fertility.
- Investigating the interplay of RBPs, epitranscriptome, and sncRNAs can uncover mechanisms of sperm function.
- This research area offers promising avenues for novel diagnostic biomarkers and therapeutic interventions for male infertility.

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

39.2K
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

01:44Termination of Translation
27.8K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

02:22Regulated mRNA Transport
7.0K
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing...

02:27Nonsense-mediated mRNA Decay
11.9K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
