Zip Codes
From Biowiki
Zip Codes are cis acting post-transcriptional regulatory motifs, often found e.g. in 3'UTRs, that direct the localization of mRNAs.
An example is the Translational Control Element (TCE) found in the 3'UTR of nanos, which establishes a posterior-anterior axis during development of fruitfly oocytes (proto-eggs). This localization of the transcript is achieved via complementary, redundant mechanisms of selective degradation and transport.
