Dynactin subunit 1 is a protein that in humans is encoded by the DCTN1 gene. ^[5]

Function

This gene encodes the largest subunit of dynactin, a macromolecular complex consisting of 23 subunits (11 individual proteins ranging in size from 22 to 150 kD). ^[6] Dynactin binds to cytoplasmic dynein, dynein cargo adaptors, and microtubules. ^[7] It is involved in a diverse array of cellular functions, including ER-to- Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis.

This subunit is commonly referred to p150-glued. ^[5] It is present in two copies per dynactin complex and forms an ≈75 nm long flexible arm that extends from the main body of dynactin. ^[6] The p150-glued arm contains binding sites for microtubules, ^[8] the microtubule plus tip binding protein EB1, ^[9] and the N-terminus of the dynein intermediate chain. ^{[10] [11]}

Alternative splicing of this gene results in at least 2 functionally distinct isoforms: a ubiquitously expressed one and a brain-specific one. Based on its cytogenetic location, this gene is considered as a candidate gene for limb-girdle muscular dystrophy. ^[12]

Interactions

DCTN1 has been shown to interact with:

• BBS4, ^[13]
• Dystonin, ^[14]
• Grb2, ^[15] and
• RAB6A. ^[16]
