Part:BBa_K3952004
LRP4 (Syndactylous Hooves)
Located within chromosome 11 of the Bos taurus genome, the LRP4 gene codes for an LDL receptor-related protein, a protein involved in the formation of the cattle's hooves. Studies have reported an inheritable syndactylous allele of the LRP4 gene that leads to congenital syndactyl (also known as mule foot) in cattle. This part contains the wildtype LRP4 gene, which differs from the syndactylous allele due to two adjacent single nucleotide polymorphisms located within exon 33 of the gene. The wildtype LRP4 contains the nucleotides CG at positions 4863 and 4864. The syndactylous LRP4 allele (part number BBa_K3952004)contains AT at positions 4863 and 4864. The substitution results in two adjacent single-nucleotide polymorphisms.
The LRP4 gene (Gene ID 504317) was located within the genomic DNA sequence of Bos taurus, using the NCBI reference assembly.
Usage and Biology
The purpose of this part is to serve as a positive control for a Flappase genetic testing system. The system requires the amplification of DNA around the polymorphism; therefore, the sequence provided is only a fragment of the Bos taurus genome. The entire sequence of the gene was not cloned to showcase where the allele would be present (exon 33), and to facilitate ease of cloning.
This part does contain the LRP4 inheritable allele. The allele is created by a substitution where nucleotides CG in the wildtype gene sequence become nucleotides AT. The substitution occurs at positions 4863 and 4864. The polymorphism resulting causes a condition known as mule foot, which refers to the fusion or non-division of the two developed digits of the bovine foot.
