General annotation (Comments)

Function

Component of the MRN complex, which plays a central role in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity and meiosis. The complex possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity, which are provided by MRE11A. RAD50 may be required to bind DNA ends and hold them in close proximity. This could facilitate searches for short or long regions of sequence homology in the recombining DNA templates, and may also stimulate the activity of DNA ligases and/or restrict the nuclease activity of MRE11A to prevent nucleolytic degradation past a given point. The complex may also be required for DNA damage signaling via activation of the ATM kinase. In telomeres the MRN complex may modulate t-loop formation By similarity. Ref.4 Ref.5

Cofactor

Binds 1 zinc ion per homodimer By similarity.

Subunit structure

Component of the MRN complex composed of two heterodimers RAD50/MRE11A associated with a single NBN. Component of the BASC complex, at least composed of BRCA1, MSH2, MSH6, MLH1, ATM, BLM, RAD50, MRE11A and NBN. Found in a complex with TERF2. Interacts with RINT1. Interacts with BRCA1 via its N-terminal domain. Interacts with DCLRE1C/Artemis By similarity.

Subcellular location

Nucleus By similarity. Chromosometelomere By similarity. Note: Localizes to discrete nuclear foci after treatment with genotoxic agents By similarity.

Tissue specificity

In adult, it is expressed at very low level in most tissues, except in heart, lung and aorta. Expressed at high level in testis. Ref.1

Developmental stage

Widely expressed. Expressed at higher level in heart, liver and thymus from E18. By neonatal day 1.5, it decreases in brain, liver, gut and skin, while it is expressed in spleen. Ref.1

Domain

The zinc-hook, which separates the large intramolecular coiled coil regions, contains 2 Cys residues that coordinate one molecule of zinc with the help of the 2 Cys residues of the zinc-hook of another RAD50 molecule, thereby forming a V-shaped homodimer. The two heads of the homodimer, which constitute the ATP-binding domain, interact with the MRE11A homodimer By similarity.

Disruption phenotype

Defects cause embryonic stem cell lethality, abnormal embryonic development and sensitivity to ionizing radiation. Ref.4

Sequence similarities

Belongs to the SMC family. RAD50 subfamily.

Contains 1 zinc-hook domain.

Alternative products

This entry describes 4 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P70388-1)

Isoform 2 (identifier: P70388-2)

The sequence of this isoform differs from the canonical sequence as follows:
     485-545: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: P70388-3)

Also known as: 3.1 kb splice variant;

The sequence of this isoform differs from the canonical sequence as follows:
     1-886: Missing.
Isoform 4 (identifier: P70388-4)

Also known as: 1.6 kb splice variant;

The sequence of this isoform differs from the canonical sequence as follows:
     485-496: ERELSKAEKNSS → IYFLELVRWLSG
     497-1312: Missing.
