23 bp exon 3 skipping in transcription rather than post-transcriptional mechanisms is a major cause of the low PTPS protein expression in human macrophages and related cell types. The exon lacking leads to a premature stop codon encoding for a shorter protein instead of the full-length functional enzyme |
