Genomic organization and alternative transcripts of nb035. (a) Genomic organization and splice variants of nb035 (H. magnipapillata genomic scaffold NW_002151021). (b) As a result of alternative splicing three proteins with different carboxy-terminal sequences are encoded. (c) Northern blot analysis using probes specific for the three splice variants (yellow lines in (a)). Asterisks indicate stop codons.
