Laminin subunit alpha-3 is a protein that in humans is encoded by the LAMA3 gene.[5][6]

Function

Laminins are basement membrane components thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. The protein encoded by this gene is the alpha-3 chain of laminin 5, which is a complex glycoprotein composed of three subunits (alpha, beta, and gamma). Alternatively spliced transcript variants encoding different isoforms have been identified.

Laminin 5 is thought to be involved in cell adhesion, signal transduction and differentiation of keratinocytes.[6]

Clinical significance

Mutations in this gene have been identified as the cause of Herlitz type junctional epidermolysis bullosa. [6]

It may be associated with Laryngoonychocutaneous syndrome.[7]

Interactions

Laminin, alpha 3 has been shown to interact with SDC2.[8]

gollark: No idea, perhaps something where the majority of data is immutable or something like that, with hardware GC.

gollark: A functional language would probably allow things to be mapped to SIMD instructions neatly as you generally do explicit high-level operations like map on immutable data.

gollark: No idea.

gollark: Erlang uses an "actor model", as I mentioned, where you have threads communicating through message queues, which is probably good for server-type applications.

gollark: CPUs also now include SIMD instructions, which C compilers have to go to great effort to attempt to use.
