ANKHD1 isoforms. The primary structures of the main ANKHD1 isoforms are illustrated. The isoform 1 was considered the canonical isoform. The protein domains and amino acid positions are indicated. The data for figure construction was obtained from Ensembl (www. ensembl.org), UniProt (www.uniprot.org) and NCBI (https://www.ncbi.nlm.nih.gov/) databases.
