Integrin beta-5 is a protein that in humans is encoded by the ITGB5 gene. [5] [6]
Integrin, beta 5 has been shown to interact with PTK2, [7] Annexin A5 [8] and PAK4. [9]
ITGB5 encodes a subunit of integrin that can interact with several alpha chains to form a variety of integrin heterodimers. It also plays a potential role in intercellular communication during tumor progression and metastasis. [10]
Elevated levels of ITGB5 have been found in patients with autosomal dominant osteopetrosis type II, a rare disease of bones. [11]
