Organism

Homo sapiens (Human)

Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	213 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	Critical for B-cell development. Ref.6
Subunit structure	Associates non-covalently with VPREB1. Ref.7
Subcellular location	Secreted Potential.
Tissue specificity	Expressed only in pre-B-cells and a special B-cell line (which is surface Ig negative). Ref.4
Involvement in disease	Defects in IGLL1 are the cause of agammaglobulinemia type 2 (AGM2) [MIM:613500]. It is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life.
Sequence similarities	Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
