GTPases and their Regulation

9.9K
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...

Regulated mRNA Transport02:22

Regulated 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...

Regulated Protein Degradation

8.9K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Biology

Background:

  • T-cell immunoglobulin and mucin domain 3 (Tim-3) is a transmembrane protein with context-dependent functions.
  • Initially identified on T cells, Tim-3 is now known to be expressed on various immune and non-immune cells.
  • Tim-3 has been implicated in both inhibitory and co-stimulatory immune responses.

Purpose of the Study:

  • To explore the multifaceted roles of Tim-3 in immune regulation.
  • To investigate the potential of Tim-3 as a therapeutic target.
  • To understand the complex in vivo functions of Tim-3.

Main Methods:

  • Analysis of Tim-3 expression patterns across different cell types.
  • Investigation of Tim-3's functional impact on immune cells.
  • Pre-clinical and clinical studies exploring Tim-3 as a therapeutic target.

Main Results:

  • Tim-3 exhibits context-dependent inhibitory and co-stimulatory functions.
  • High Tim-3 expression is observed on exhausted T cells in chronic infections and tumors.
  • Tim-3 interacts with other checkpoint molecules like PD-1.

Conclusions:

  • Tim-3 plays a complex role in immune responses, distinct from other checkpoint inhibitors.
  • Further research is needed to fully elucidate Tim-3's in vivo functions.
  • Tim-3 represents a significant therapeutic target for immune-related diseases.
