Protein attributes

Sequence length	653 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May have an E3 ubiquitin ligase activity. May play a significant role in mediating the biological activity of the HIV-1 Tat protein in vivo. Binds specifically to the activation domain of HIV-1 Tat and can also interact with the HIV-2 and EIAV Tat proteins in vivo.
Subcellular location	Nucleus.
Tissue specificity	Spleen, thymus, prostate, testis, ovary, intestine, colon and skeletal muscle. Ref.7
Involvement in disease	Defects in TRIM32 are the cause of limb-girdle muscular dystrophy type 2H (LGMD2H) [MIM:254110]; also known as muscular dystrophy Hutterite type. LGMD2H is an autosomal recessive degenerative myopathy characterized by pelvic girdle, shoulder girdle and quadriceps muscle weakness. Clinical phenotype and severity are highly variable. Disease progression is slow and most patients remain ambulatory into the sixth decade of life. Ref.7 Ref.9 Defects in TRIM32 are the cause of Bardet-Biedl syndrome type 11 (BBS11) [MIM:209900]. Bardet-Biedl syndrome (BBS) is a genetically heterogeneous, autosomal recessive disorder characterized by usually severe pigmentary retinopathy, early onset obesity, polydactyly, hypogenitalism, renal malformation and mental retardation. Secondary features include diabetes mellitus, hypertension and congenital heart disease. A relatively high incidence of BBS is found in the mixed Arab populations of Kuwait and in Bedouin tribes throughout the Middle East, most likely due to the high rate of consaguinity in these populations and a founder effect. Ref.9 Ref.8
Sequence similarities	Belongs to the TRIM/RBCC family. Contains 1 B box-type zinc finger. Contains 5 NHL repeats. Contains 1 RING-type zinc finger.
