RESEARCH: STP6-SUGAR-TRANSPORT
FOLDING PROJECT #17953 PROFILE

STP6 is a protein that helps plants move sugar into their pollen. This project wants to figure out how STP6 works so we can understand better how plants use sugar for growth.

Note: This TLDR is a simplication and may not be 100% accurate.

STP6 (Sugar Transport Protein 6) is a high-affinity proton/hexose symporter that primarily functions as a plasma membrane sugar transporter.

It is mainly expressed in pollen, where it plays a critical role in importing sugars like glucose and fructose to support late pollen maturation and pollen tube germination.

These projects aim to understand the molecular mechanism of sugar transport in STP6.

STP6

Sugar Transport Protein 6

STP6 is a protein that helps plants transport sugar into pollen. This is important for the growth and development of pollen.

---

Sugar Transport Protein

A protein that facilitates the movement of sugars across cell membranes.

Sugar transport proteins are essential for plants to move sugars around their bodies. They help deliver sugars to where they're needed for growth and energy.

---

Proton/hexose symporter

A type of membrane protein that uses a proton gradient to transport hexose sugars across the membrane.

This protein uses energy from a proton gradient to move sugar molecules across a cell membrane. It's like a door that opens and closes to let in sugar.

---

Plasma membrane

The outer membrane of a cell that separates the cell's interior from its external environment.

This is the outer boundary of a cell. It controls what goes in and out of the cell.

---

Pollen

The male reproductive cell of a plant, typically produced in the anther of a flower.

Pollen is like the sperm of a plant. It's needed for plants to reproduce.

---

Glucose

A simple sugar that is a primary source of energy for plants and animals.

Glucose is a type of sugar that plants use for energy. It's also an important source of energy for people and animals.

---

Fructose

A simple sugar that is found in fruits and honey.

Fructose is another type of sugar. It's often found in fruits and sweet foods.

---

Pollen tube

A tubular structure that grows from a pollen grain after it lands on the stigma of a flower.

This tube helps deliver the male genetic material from the pollen to the female part of a flower.

---

Germination

The process by which a seed sprouts and begins to grow.

This is when a seed starts to grow into a plant.
