DCTN4

DCTN4 (Dynactin Subunit 4) is a Protein Coding gene. Diseases associated with DCTN4 include Cystic Fibrosis. Among its related pathways are COPI-independent Golgi-to-ER retrograde traffic and Transport to the Golgiand subsequent modification. Gene Ontology (GO) annotations related to this gene include protein N-terminus binding.

dynactin 4

Could have a dual role in dynein targeting and in ACTR1A/Arp1 subunit of dynactin pointed-end capping. Could be involved in ACTR1A pointed-end binding and in additional roles in linking dynein and dynactin to the cortical cytoskeleton.

Cytoskeleton; Centrosome; Stress fiber; Cell cortex; sarcomere. Has a punctate cytoplasmic distribution as well as centrosomal distribution typical of dynactin (PubMed:10671518). Overexpression in cultured mammalian cells revealed colocalization with cortical actin, stress fibers, and focal adhesion sites, sites of potential interaction between microtubules and the cell cortex (By similarity). In skeletal muscles, costamere localization requires the presence of ANK2 (By similarity).
