    • We searched for functional homologues of the four subfamilies of vertebrate cytoplasmic intermediate filament (IF) proteins in the cephalochordate Branchiostoma. The epidermis contains in addition to IF proteins C2 and D1 two novel IF proteins E1 and E2. Both sequence comparisons as well as the obligatory heteropolymer formation by the recombinant proteins identify E1 as a type I keratin and E2 and D1 as type II keratins. In contrast the non‐epidermal B1 forms as type III homologue… CONTINUE READING
