Question

1. _______ ________ is an intramolecular post-translational process that allows for self-catalytic removal of specific amino acid sequences.
2. Within the endoplasmic reticulum, ______________ ___________ recognizes misfolded or unassembled proteins and transports them back to the cytosol.

Answer 1

1. Protein splicing

The protein splicing is a process of intramolecular reaction during which the protein segment called "intein" is removed from the precursor protein with the process of ligation of "exteins". Protein splicing is an intramolecular post-translational process that allows for self-catalytic removal of specific amino acid sequences.

2. ERAD

ERAD : Endoplasmic-reticulum-associated protein degradation

Within the endoplasmic reticulum, ERAD recognizes misfolded or unassembled proteins and transports them back to the cytosol.
