About This Section

EntrezGene summary for DAZ2:
This gene is a member of the DAZ gene family and is a candidate for the human Y-chromosomal
azoospermia factor (AZF). Its expression is restricted to premeiotic germ cells, particularly in
spermatogonia. It encodes an RNA-binding protein that is important for spermatogenesis. Four
copies of this gene are found on chromosome Y within palindromic duplications; one pair of genes
is part of the P2 palindrome and the second pair is part of the P1 palindrome. Each gene contains
a 2.4 kb repeat including a 72-bp exon, called the DAZ repeat; the number of DAZ repeats is
variable and there are several variations in the sequence of the DAZ repeat. Each copy of the gene
also contains a 10.8 kb region that may be amplified; this region includes five exons that encode
an RNA recognition motif (RRM) domain. This gene contains one copy of the 10.8 kb repeat.
Alternative splicing results in multiple transcript variants encoding different isoforms.

UniProtKB/Swiss-Prot: DAZ2_HUMAN, Q13117
Function: RNA-binding protein that plays an essential role in spermatogenesis. May act by binding
to the 3'-UTR of mRNAs and regulating their translation

About This Section

UniProtKB/Swiss-Prot: DAZ2_HUMAN, Q13117 (See protein sequence)
Recommended Name: Deleted in azoospermia protein 2  
Size: 558 amino acids; 63111 Da
Subunit: Forms a heterodimer with BOLL and DAZL. Interacts with PUM2, DAZAP1, DAZAP2, DZIP1 and
DZIP3
Subcellular location: Cytoplasm. Nucleus. Note=Predominantly cytoplasmic. Nuclear at some stages of
spermatozoide development. Localizes both to the nuclei and cytoplasm of spermatozoide
differentiation. Nuclear in fetal gonocytes and in spermatogonial nuclei. It then relocates to the
cytoplasm during male meiosis
Miscellaneous: The DAZ proteins (DAZ, DAZ2, DAZ4 and DAZ4) are all encoded by a strongly repeated
region of the Y chromosome, in two clusters each comprising an inverted pair of DAZ genes. They
are very similar, which gives their indidual characterization difficult. Thus, most experiments do
not discriminate between the different members. One can therefore suppose that reported
interactions with a DAZ protein involve all the 4 proteins
