Human Laminin subunit alpha-4 (LAMA4) ELISA Kit

Laminin subunit alpha-4 isalpha chain isoform laminin, alpha 4. The domain structure of alpha 4 is similar to that of alpha 3, both of which resemble truncated versions of alpha 1 and alpha 2, in that approximately 1,200 residues at the N-terminus (domains IV, V and VI) have been lost. Laminin, alpha 4 contains the C-terminal G domain which distinguishes all alpha chains from the beta and gamma chains. The RNA analysis from adult and fetal tissues revealed developmental regulation of expression, however, the exact function of laminin, alpha 4 is not known. Tissue-specific utilization of alternative polyA-signal has been described in literature. Also, alternative splicing involving the first intron in the 5' UTR, and laminin alpha 4 like isoforms have been noted, however, the full-length nature of these products is not known.
