[5] This gene encodes a spectrin repeat containing protein expressed in skeletal and smooth muscle, and peripheral blood lymphocytes, that localizes to the nuclear membrane.

[5] Enaptin is a nuclear envelope protein found in human myocytes and synapses, which is made up of 8,797 amino acids.

The molecular weight of the mature protein is approximately 1,011 kDa, and it has a theoretical pI of 5.38.

It has a theoretical Instability Index (II) of 51.63, indicating that it would be unstable in a test tube.
