Repurposing a pore: highly conserved perforin-like proteins with alternative mechanisms
1Division of Structural Biology, Wellcome Trust Centre for Human Genetics, University of Oxford, Roosevelt Drive, Oxford OX3 7BN, UK.
Summary
Pore-forming proteins, like the membrane attack complex/perforin (MACPF) family, are crucial in defense and disease. Some MACPF proteins may use novel mechanisms beyond pore formation in development.
Area of Science:
- Biochemistry
- Cell Biology
- Immunology
Background:
- Pore-forming proteins are vital in host defense and pathogen attack.
- The membrane attack complex/perforin (MACPF) family and cholesterol-dependent cytolysins are major classes of pore-forming proteins.
- Understanding MACPF protein function is key to various biological processes.
Purpose of the Study:
- To review the structure and common pore-formation mechanisms of MACPF proteins.
- To discuss MACPF proteins involved in membrane remodeling and pore formation.
- To highlight less-studied MACPF members, astrotactin and BMP/RA-induced neural proteins, in developmental roles.
Main Methods:
- Literature review of MACPF protein structure and function.
- Analysis of known MACPF protein mechanisms.
- Focus on specific MACPF family members in developmental contexts.
Main Results:
- MACPF proteins share common structural features and pore-formation mechanisms.
- Several MACPF proteins are implicated in membrane attack or remodeling.
- Astrotactin and BMP/RA-induced neural proteins, conserved MACPF members, may function via alternative, non-pore-forming mechanisms in development.
Conclusions:
- MACPF proteins exhibit diverse functions beyond pore formation.
- Astrotactin and BMP/RA-induced neural proteins represent a distinct functional class within the MACPF family.
- Further research is needed to elucidate the non-pore-forming roles of these developmental MACPF proteins.

02:53Conservative Site-specific Recombination and Phase Variation
7.0K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

01:57Protein Complexes with Interchangeable Parts
3.0K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

01:21Structure of Porins
4.0K
Mitochondria, chloroplasts, and gram-negative bacteria have transmembrane, beta-barrel proteins called porins to mediate the free diffusion of ions and metabolites across the membrane. Mitochondrial porin precursors contain conserved amino acid sequences called beta signals at their C-terminal. Beta signals have a motif of PoXGXXHyXHy (Po-Polar, X-Any amino acid, G-Glycine, Hy-LargeHydrophobic), which are crucial for precursor recognition to initiate precursor assembly. Beta-barrel...

02:26Conservation of Protein Domains Over Different Proteins
14.8K
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

01:39Mitochondrial Precursor Proteins
3.8K
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.

02:32Exon Recombination
4.2K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
