The BEACH domain was described in the BEIGE protein (D1035670) and in the highly homologous CHS protein. The BEACH domain is usually followed by a series of WD repeats. The function of the BEACH domain is unknown. Length = 280
>gnl|CDD|216896 pfam02138, Beach, Beige/BEACH domain
>gnl|CDD|100117 cd06071, Beach, BEACH (Beige and Chediak-Higashi) domains, implicated in membrane trafficking, are present in a family of proteins conserved throughout eukaryotes
This group contains human lysosomal trafficking regulator (LYST), LPS-responsive and beige-like anchor (LRBA) and neurobeachin. Disruption of LYST leads to Chediak-Higashi syndrome, characterized by severe immunodeficiency, albinism, poor blood coagulation and neurologic problems. Neurobeachin is a candidate gene linked to autism. LBRA seems to be upregulated in several cancer types. It has been shown that the BEACH domain itself is important for the function of these proteins. Length = 275

>PF02138 Beach: Beige/BEACH domain; InterPro: IPR000409 The BEACH domain is found in eukaryotic proteins that have diverse cellular functions ranging from lysosomal traffic to apoptosis and cytokinesisin vesicle trafficking, membrane dynamics, and receptor signaling
The name BEACH is derived from beige and Chediak-Higashi syndrome (CHS). CHS is a rare, autosomal recessive disorder that can cause severe immunodeficiency and albinism in humans and other mammals, and beige is the name for the CHS disease in mice [, ]. The BEACH domain was first described in the lysosomal-trafficking regulators Beige protein and its human homologue CHS protein Q99698 from SWISSPROT. It is also found in distantly related proteins like, for example, the FAN proteins O35242 from SWISSPROT and Q92636 from SWISSPROT which are factor associated with neutral sphingomyelinase activation []. It has also been described in Dictyostelium proteins Lvs []. The BEACH domain is usually followed by a series of WD repeats (PDOC00574 from PROSITEDOC). The function of the BEACH domain is unknown.; PDB: 1MI1_B 1T77_C.
