MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a 50-kD subunit of dynactin, a macromolecular complex consisting of 10-11 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein. 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 present in 4-5 copies per dynactin molecule. It contains three short alpha-helical coiled-coil domains that may mediate association with self or other dynactin subunits. It may interact directly with the largest subunit (p150) of dynactin and may affix p150 in place. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2012]

Protein Function and Prediction

Dctn2 encodes p50/dynamitin, a subunit of the multiprotein dynactin complex.  Dynactin associates with dynein to facilitate minus-end-directed movement along microtubules (1). Studies have shown that p50 is required for the stabilization and attachment of the Arp1 rod and the shoulder/sidearm of dynactin (1). Amino acids 1-91 of p50 have been shown to be critical for dynactin function (1). Three coiled-coil motifs [aa 105-136, 219-251, and 281-308 (2)] facilitate the oligomerization of p50 as well as the association of p50 with other dynactin subunits (1;3).
