Secondry Information

Presence in other biological fluids/tissue/cells Tissues with the highest expression of the RRas2 mRNA included the lung and testis ;Tissues with moderate expression levels included different parts of the gut, the bladder, the white adipose tissue, the ovary, and, as expected , hematopoietic tissues such as the thymus and spleen;. Other tissues, such as the heart, trachea, a number of glands (adrenal, salivary, mammary, bulbourethral), kidney, eyes, skin, and the brain, showed lower levels of expression; Tissues with very low expression levels included the tongue, liver, skeletal muscle, and brown adipose
Protein Function Member of the Ras GTPase superfamily; role in signal transduction, membrane trafficking, nuclear export/import, and cytoskeletal dynamics; critical for both embryonic and postnatal viability
Significance in milk important for proper mammary gland development
PTMs exhibited increased lysine fatty acylation in mouse embryonic fibroblast and Human Embryonic Kidney
Significance of PTMs Lysine fatty acylation promotes the plasma membrane localization of R-Ras2 and its interaction with phosphatidylinositol 3-kinase PI3K, leading to activated Akt and increased cell proliferation
