Mitochondrial Protein Sorting01:39

Mitochondrial Protein Sorting

4.3K
Mitochondria are double-membrane organelles of the eukaryotes involved in cellular metabolism, signaling, ATP synthesis, and programmed cell death.  Each of these processes requires specific proteins and enzymes that must be correctly sorted to the right mitochondrial subcompartment for the proper functioning of the organelle.
Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...

Protein Transport into the Inner Mitochondrial Membrane01:34

Protein Transport into the Inner Mitochondrial Membrane

3.5K
Nuclear encoded mitochondrial precursors are imported to the inner membrane in a multistep process involving two separate translocons, TIM22 and TIM23. TIM23 is a cation-selective pore that remains closed by the N terminal segment of the protein. Negative charges on the TIM23 act as a receptor for the incoming precursor, pulling the positively charged matrix-targeting sequence for peptide insertion and translocation.
Transport of mitochondrial precursors across the TIM23 channel is driven by...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

8.8K
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,...

Transcellular Transport of Solutes01:23

Transcellular Transport of Solutes

4.0K
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...

ABC Transporters: Importer01:27

ABC Transporters: Importer

2.6K
ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:

Tail-anchoring of Proteins in the ER Membrane01:45

Tail-anchoring of Proteins in the ER Membrane

2.8K
Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

Summary

Ancient Mesopotamians show genetic links to India. Mitochondrial DNA (mtDNA) analysis suggests South and Northeast India as the source, likely through Tamil merchants in the Indo-Roman trade.

Area of Science:

  • Genetics
  • Ancient History
  • Archaeology

Background:

  • Mitochondrial DNA (mtDNA) analyses suggest a genetic connection between ancient Mesopotamians and the Indian subcontinent.
  • The precise origin of ancient Mesopotamians remains debated, with theories including migration or trade involvement.

Purpose of the Study:

  • To identify the specific Indian population(s) linked to the ancient Mesopotamian gene pool.
  • To investigate the role of potential migration and trade in shaping ancient Mesopotamian genetic ancestry.

Main Methods:

  • Screening of 15,751 mitochondrial DNA samples from various Indian populations.
  • Comparative analysis of ancient Mesopotamian mtDNA with Indian mtDNA data.

Main Results:

  • Mitochondrial DNA data indicates South India (Tamil Nadu) and Northeast India as potential sources for the ancient Mesopotamian mtDNA gene pool.
  • The findings suggest that Tamil merchants involved in the Indo-Roman trade may have contributed to the ancient Mesopotamian mtDNA.

Conclusions:

  • Ancient Mesopotamian genetic ancestry has links to South and Northeast India.
  • Tamil merchants likely played a significant role in the genetic exchange between India and Mesopotamia during the ancient period.
