Summary
Roco proteins, featuring Roc and COR domains, are crucial in cell processes and evolution. Mutations in human Roco genes, like LRRK2, are linked to Parkinson disease, highlighting their complex roles.
Area of Science:
- Molecular Biology
- Evolutionary Biology
- Biochemistry
Background:
- Roco proteins possess a conserved supradomain with Roc (Ras-like GTPase) and COR domains.
- They are found across prokaryotes and eukaryotes, originating from Dictyostelium discoideum.
- Additional domains like kinase and regulatory elements are often present.
Purpose of the Study:
- To review evolutionary, biochemical, and functional data on the Roco protein family.
- To explore the structural characteristics and phylogenetic distribution of Roco proteins.
- To discuss the implications of Roco protein function and mutations in human diseases.
Main Methods:
- Literature review of existing evolutionary, biochemical, and functional data.
- Analysis of conserved domains (Roc, COR, kinase) and their interactions.
- Examination of phylogenetic distribution and disease associations.
Main Results:
- Roco proteins exhibit diverse functions, including roles in cell division, chemotaxis, and development in Dictyostelium.
- Mutations in human Roco genes, notably LRRK2, are implicated in familial Parkinson disease, epilepsy, and cancer.
- Biochemical data suggest intramolecular activation of kinase domains by Roc domains.
Conclusions:
- Roco proteins may function as independent signal transduction units.
- Disease-associated mutations in LRRK2 can enhance kinase activity.
- The Roco family represents a significant area of study due to its fundamental roles and disease relevance.

01:14Rab Proteins
Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

02:47Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...

Overview
01:24Protein Organization
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.
