Abstract.
The secretory carrier membrane proteins (SCAMPs) are highly conserved integral vesicle membrane components of the post-Golgi secretory and endocytic pathways. We have isolated and characterized the porcine SCAMP1 cDNA and gene coding for a variant of the SCAMP family. The SCAMP1 cDNA has a length of 3827 bp including a 133-bp 5′ and 2701-bp 3′ untranslated region. The mRNA has an open reading frame of 1014 nt coding for a protein of 338 amino acids with a calculated molecular mass of 37.9 kDa and a pI of 7.9. The porcine SCAMP1 is 97.04% identical with the human and rat paralogs, respectively. The SCAMP1 gene consists of nine exons with sizes ranging from 78 to 2842 bp and spans at least 70 kb of genomic DNA on porcine Chromosome (Chr) 2q21–q22. The promoter of the SCAMP1 gene is TATA-box-less, and transcription starts at a G-nucleotide 133 nt upstream the start codon.
