Paper: Site Selective Antibody-Oligonucleotide Conjugation via Microbial Transglutaminase.

https://www.mdpi.com/1420-3049/24/18/3287

This paper describes using a microbial transglutamase to put an azide group in a peptide onto the terminal carboxylic acid of an antibody protein, then using Cu-free click chemistry to affix an antisense oligo at that site. They didn't use Morpholinos, but in principle one could.

Targeting mitochondrially-encoded circular RNAs in the cytosol: mitochondrial protein uptake suppression

Here is an interesting report of Morpholinos targeting mitochondrially-encoded circular RNAs in the cytosol to prevent RNA-chaperoned protein uptake into the mitochondria.

Their mutants and their morphants show difering phenotypes: they suggest that more time is needed for compensation, mutants having enough but not morphants

These investigators suggest a reason their mutants and their morphants show different phenotypes. The mutant embryos have had time enough to compensate for the knockdowns, hiding aspects of the loss-of-funciton phenotype, while the acute knockdown of the Morpholino shows a phenotype during time insufficient for compensation.
