Question

The following is true regarding cotranslational translocation:

a hydrophobic core within the SRP binds to a hydrophobic region on the N-terminal side of the Signal Sequence

a hydrophillic core within the SRP binds to a hydrophobic region on the N-terminal side of the Signal Sequence

a hydrophillic core within the SRP binds to a hydrophillic region on the N-terminal side of the Signal Sequence

a hydrophobic core within the SRP binds to a hydrophillic region on the N-terminal side of the Signal Sequence

a hydrophobic core within the SRP binds to a hydrophobic region on the N-terminal side of the Signal Sequence

a hydrophillic core within the SRP binds to a hydrophobic region on the N-terminal side of the Signal Sequence

a hydrophillic core within the SRP binds to a hydrophillic region on the N-terminal side of the Signal Sequence

a hydrophobic core within the SRP binds to a hydrophillic region on the N-terminal side of the Signal Sequence

Explanation / Answer

cotranslational translocation is used by several proteins like secretory and membrane bound proteins or proteins that reside out of endoplasmic reticulum , golgibodies or endosomes. The initiation of process occurs by recognition of N - terminal signal peptide sequence which is a 6 - 12 hydrophobic residues that bind to hydrophobic core of signal recognition particle (SRP). Hence, option 1 is correct.
