Summary: Enables lamin binding activity. Involved in several processes, including egg-laying behavior; nuclear migration along microtubule; and vulval development. Located in nuclear inner membrane. Is expressed widely. Human ortholog(s) of this gene implicated in spermatogenic failure 16. Orthologous to several human genes including SUN2 (Sad1 and UNC84 domain containing 2) and SUN3 (Sad1 and UNC84 domain containing 3). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

SUN-KASH bridges are only required to maintain nuclear envelope spacing in cells subjected to increased mechanical forces.
Title: The SUN protein UNC-84 is required only in force-bearing cells to maintain nuclear envelope architecture.
targeting UNC-84 requires an initial step that actively transports UNC-84 from the peripheral endoplasmic reticulum to the nuclear envelope
Title: Multiple mechanisms actively target the SUN protein UNC-84 to the inner nuclear membrane.
UNC-84 and UNC-83, the KASH and SUN domain proteins, bridge the nuclear envelope, connecting the nuclear lamina to cytoskeletal components.
Title: UNC-83 IS a KASH protein required for nuclear migration and is recruited to the outer nuclear membrane by a physical interaction with the SUN protein UNC-84.
