Summary
Honeybee memory formation involves cAMP-dependent kinase (PKA). Researchers identified PKA and CREB/CREM family genes in the honeybee genome, revealing one CREB/CREM gene and multiple PKA genes.
Area of Science:
- Molecular Biology
- Neuroscience
- Genomics
Background:
- cAMP-dependent kinase (PKA) is vital for long-term memory in honeybees.
- cAMP response element binding protein (CREB) is a potential PKA substrate involved in memory.
- Understanding these molecular pathways is key to deciphering memory formation.
Purpose of the Study:
- To identify and characterize genes encoding PKA and CREB/CREM family members in the honeybee genome.
- To analyze the phylogenetic relationships of these identified genes.
Main Methods:
- Genome-wide search for PKA and CREB/CREM family genes in Apis mellifera.
- Phylogenetic analysis comparing honeybee genes with Drosophila and human counterparts.
Main Results:
- Identified two genes for PKA regulatory subunits and three for catalytic subunits.
- Discovered eight bZIP protein genes, with only one belonging to the CREB/CREM family.
- Established phylogenetic relationships among honeybee, Drosophila, and human genes.
Conclusions:
- The honeybee genome contains multiple PKA genes and a single CREB/CREM gene, suggesting a conserved but specific role in memory.
- Phylogenetic analysis provides insights into the evolutionary history of these key memory-related genes.

01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
01:58Prokaryotic Transcriptional Activators and Repressors
The organization of prokaryotic genes in their genome is notably different from that of eukaryotes. Prokaryotic genes are organized, such that the genes for proteins involved in the same biochemical process or function are located together in groups. This group of genes, along with their regulatory elements, are collectively known as an operon. The functional genes in an operon are transcribed together to give a single strand of mRNA known as polycistronic mRNA.

02:53CRISPR and crRNAs
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

01:25cAMP-dependent Protein Kinase Pathways
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

02:02Cis-regulatory Sequences
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
