Some proteins that are different between dogs and horses include:
1. Hemoglobin: Dogs have a different type of hemoglobin compared to horses, which allows them to carry oxygen more efficiently in their blood.
2. Immunoglobulins: Dogs and horses have different types of immunoglobulins, which are antibodies that help the immune system fight off infections and diseases.
3. Myoglobin: Dogs have higher levels of myoglobin in their muscles compared to horses, which helps them with endurance and stamina.
4. Keratin: Dogs and horses have different types of keratin in their hair and hooves, which gives them their unique physical characteristics.
5. Insulin: Dogs and horses have different levels of insulin in their bodies, which helps regulate their blood sugar levels and metabolism.

Structural Proteins
- Myosin and actin: Different isoforms expressed, resulting in variations in muscle fiber type and contractile properties. - Collagen: Different types and ratios of collagen in various tissues, contributing to tissue stiffness, elasticity, and strength. - Elastin: Differences in the structure and distribution of elastin fibers in the skin and blood vessels.
Enzymes
- Amylase: Dogs have two pancreatic amylase isoforms, while horses have only one. - Lipase: Horses have higher pancreatic lipase activity compared to dogs. - Cytochrome P450 enzymes: Different isoforms expressed, leading to variations in drug metabolism and detoxification.
Hormones
- Insulin: Dogs have lower insulin sensitivity compared to horses. - Glucagon: Horses have higher glucagon levels and a more pronounced glucagon response to fasting. - Growth hormone: Horses have higher growth hormone levels and a different pattern of secretion.
Blood Proteins
- Hemoglobin: Horses have a higher concentration of hemoglobin in their red blood cells. - Albumin: Horses have lower levels of albumin in their blood. - Fibrinogen: Horses have higher fibrinogen levels and a faster clotting time.
Other Proteins
- Keratin: Different types and arrangements of keratin proteins in hair, hooves, and skin. - Immunoglobulins: Horses have higher levels of certain immunoglobulin subclasses, such as IgG and IgA. - Cytokines and chemokines: Differences in the expression and activity of immune mediators. - Transporters: Different levels of expression and function of various nutrient and drug transporters in cells.
