The CUG initiation codon for cardiac expression of Sdf-1c is downstream of the 1st in-frame AUG codon, a element shared only with the option translation initiation of osteopontin (Opn)
Sdf-1c is made up of an NLS/NoLS that we have mapped to the exon-4-encoded C-terminal domain. The existence of a secretory sign motif and a NLS in the very same…
