Summary
Phosphatidylinositol transfer proteins (PITPs) like yeast Sec14p are crucial for selective lipid transport. This review explores five Sec14p homologues (Sfh proteins) involved in diverse cellular functions.
Area of Science:
- Cell Biology
- Biochemistry
- Molecular Biology
Background:
- Lipid transport is essential for eukaryotic organelle biogenesis, requiring precise lipid composition.
- Mechanisms for lipid sorting and movement within cells are not fully understood.
- Phosphatidylinositol transfer proteins (PITPs) are implicated in maintaining non-random lipid distribution.
Purpose of the Study:
- To review the roles of five yeast Sec14p homologues, termed Sfh proteins.
- To highlight their distinct subcellular localizations and physiological functions.
- To connect Sfh proteins to lipid metabolism, signaling, and membrane trafficking.
Main Methods:
- Sequence homology analysis to identify Sfh proteins.
- Literature review of studies on Sfh protein localization and function.
- Comparative analysis with Sec14p function in Saccharomyces cerevisiae.
Main Results:
- Identified five yeast proteins (Sfh proteins) with significant sequence homology to Sec14p.
- These Sfh proteins exhibit diverse subcellular localizations.
- Sfh proteins are involved in lipid metabolism, phosphoinositide signaling, and membrane trafficking.
Conclusions:
- Sfh proteins represent a diverse group with critical roles in cellular lipid homeostasis.
- Understanding Sfh proteins provides insights into fundamental processes of lipid transport and organelle function.
- Further research on Sfh proteins can elucidate complex cellular signaling and trafficking pathways.

01:28Yeast Signaling
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
01:19Septins
Septins are protein filaments forming the cytoskeleton along with the microtubules, microfilaments, intermediate filaments, and other accessory proteins. In 1971 while studying the cell division cycle in mutant Saccharomyces cerevisiae Harwell et al. first identified the septin-related genes playing a crucial role in yeast cytokinesis. Fluorescence microscopy revealed that these proteins localize at the budding neck as rings. These ring-like proteins were then named Septins by John Pringle, and...
01:57Protein Complexes with Interchangeable Parts
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.

01:33Overview of Secretory Vesicles
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

01:28Protein Translocation Machinery on the ER Membrane
The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the translocon complex.

01:45Tail-anchoring of Proteins in the ER Membrane
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...
