Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Mitochondrial Precursor Proteins

Mitochondrial Precursor Proteins

Mitochondrial precursors are partially unfolded or loosely folded polypeptide chains. Newly synthesized precursors are inhibited from spontaneously folding into their native conformation by the cytosolic chaperones, heat shock proteins 70 (Hsp70), and mitochondrial import stimulation factors (MSFs). Precursors bound to MSFs are guided to the TOM70-TOM37 receptors, while precursors bound to Hsp70 chaperones are targetted to TOM20-TOM22 receptor complexes.
Most of the mitochondrial...

Leaky Scanning

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Translocation of Proteins into the Mitochondria

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Signal Sequences and Sorting Receptors

Signal Sequences and Sorting Receptors

Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...

Area of Science:

Malariology
Genomics
Proteomics

Background:

Malaria is a severe human disease caused by five Plasmodium species, notably Plasmodium falciparum.
The P. falciparum genome contains numerous proteins with repetitive low-complexity sequences.
These sequences exhibit dynamic expansion/contraction and rapid evolution.

Purpose of the Study:

To explore the diverse roles of low-complexity repetitive sequences in P. falciparum.
To understand the functional significance of these sequences in the parasite's life cycle and host interactions.

Main Methods:

Bioinformatic analysis of P. falciparum genome and proteome.
Review of existing literature on repetitive sequences and protein function.

Main Results:

Approximately 25% of P. falciparum proteins contain simple repeats like poly-asparagine tracts.
More complex amino acid repeats are prevalent across various parasite protein families.
While some repetitive sequences may be non-functional, many are increasingly recognized as critical for protein function.

Conclusions:

Repetitive sequences are integral to P. falciparum biology.
These sequences mediate crucial functions including protein-protein interactions.
They are vital for parasite survival mechanisms, such as evading the host immune system.
