Tissue SpecificityStrongly expressed in pancreas, kidney (adult and fetal), skeletal muscle, melanocytes and keratinocytes (PubMed:22649030). Expressed at lower levels in placenta and heart. Weakly expressed in lung, liver and brain (adult and fetal) (PubMed:22649030). {ECO:0000269|PubMed:22649030}.;
[Isoform 2]: Represents 5-20 % of CTNS transcripts, with the exception of the testis that expresses both isoforms in equal proportions. {ECO:0000269|PubMed:22649030}.
