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.
