Chapter 7b: Protein Transport and Synthesis

These flashcards cover key terms and concepts related to protein transport and synthesis as discussed in Chapter 7b.

Signal sequences

Short peptide sequences that direct the transport of proteins to their correct location.

Post-translational transport

The transport of proteins that occurs after they have been fully synthesized.

Transmembrane protein

A protein that spans the membrane of a cell or organelle, often involved in signaling or transport.

Golgi apparatus

An organelle that functions in protein sorting, modification, and packaging for transport.

SRP (Signal Recognition Particle)

A protein-RNA complex that directs the ribosome to the endoplasmic reticulum by binding to the ER signal sequence.

Signal peptidase

An enzyme that cleaves signal sequences from proteins during their transport.

Chaperone proteins

Proteins that assist in the folding and transport of other proteins, ensuring they maintain proper structure.

Nuclear localization signal sequence

A sequence that directs proteins to the nucleus, allowing them to pass through nuclear pores.
