The protein encoded by this gene belongs to the TRIM
protein family. It has multiple zinc finger motifs and a leucine
zipper motif. It has been proposed to form homo- or heterodimers
which are involved in nucleic acid binding. Thus, it may act as a
transcriptional regulatory factor involved in carcinogenesis and/or
differentiation. It may also function in the suppression of
radiosensitivity since it is associated with ataxia telangiectasia
phenotype.
