PF04086Signal recognition particle, alpha subunit, N-terminal (SRP-alpha_N)Signal recognition particle, alpha subunit, N-terminalSRP is a complex of six distinct polypeptides and a 7S RNA that is essential for transferring nascent polypeptide chains that are destined for export from the cell to the translocation apparatus of the endoplasmic reticulum (ER) membrane [1]. SRP bin ...SRP is a complex of six distinct polypeptides and a 7S RNA that is essential for transferring nascent polypeptide chains that are destined for export from the cell to the translocation apparatus of the endoplasmic reticulum (ER) membrane [1]. SRP binds hydrophobic signal sequences as they emerge from the ribosome, and arrests translation. This entry represents the N-terminal domain of the alpha subunit (SRPA), which is responsible for tethering the SRPA to the ER membrane bound subunit beta (SRPB or SRbeta) [2,3].
