Cooperative Binding of Transcription Regulators02:13

Cooperative Binding of Transcription Regulators

6.0K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Protein Complexes with Interchangeable Parts

2.1K
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.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

5.0K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

Structure of Cadherins01:25

Structure of Cadherins

4.0K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

  • The cap-binding complex (CBC) is a key mediator of 7mG functions.

Purpose of the Study:

  • To review the mechanisms by which CBC mediates gene expression.
  • To discuss how CBC coordinates multiple gene expression events.

Main Methods:

  • Literature review of studies on CBC function.
  • Analysis of signaling pathways influencing CBC.

Main Results:

  • CBC plays a vital role in transcription, splicing, transcript export, and translation.
  • Signaling pathways can regulate gene expression by modulating CBC activity.

Conclusions:

  • CBC is a central coordinator of eukaryotic gene expression.
  • Understanding CBC mechanisms provides insights into gene regulation.
